lava: Remove apt update & upgrade from lava setup

The `apt-get upgrade` will block waiting for user input unless `-y` is
specified, causing builds to time out when there are actually updates
to perform.

Rather than forcing the command to run in non-interactive mode, I
decided to remove the update and ugprade. My principal reasoning is
that most of the jobs no longer require extra packages to be installed
at run time - they are included instead in the rootfs.

lava: Install vlttng inside a venv

A number of the lava jobs were failing as the python tests couldn't
import the `bt2` module. While it may be possible to improve the
behaviour of vlttng to better address the situation two elements
combine to make the process work more systematically:

* Install `vlttng` inside a venv instead of using the
`--break-system-packages` option: once activated, this will set an
initial value for the `PYTHONPATH` environment variable
* When `vlttng` is invoked, since `PYTHONPATH` is no longer empty, the
value will be updated correctly.

In the case of the new rootfs, it also appears to be necessary to
ensure that `setuptools` is using `distutils` from Python stdlib,
although the module is deprecated and will be removed in Python 3.12

jjb: remove -DDEBUG from coverity CFLAGS

As far as I know we don't use this define and it conflicts with a
loglevel enum value in babeltrace.

ansible: Use HTTP/1.1 for git http operations on Debian bookworm

When using HTTP/2 for git operations, git's use of libcurl can result
in deadlocks with libcurl 7.84-8.4 as libcurl may call the read
callback multiple times after EOF.

jjb: Add older LTS kernel versions

lttng-modules stable-2.13 supports Linux >= 3.0 at this time. When
`dev_review_` jobs for this branch are run, the version ranges are set
with `kverceil` and `kverfloor`, then filtered according to
`lts-head`. Since only more recent LTS kernels were added to
`lts_kversions`, CI tests weren't running against as wide of a range
of kernels as suggested by the project's support matrix.

ansible: lxd: Disable secureboot on the ci-rootnode profile

The rootnodes are typically VMs (currently managed via libvirt rather
than lxd). However, the profile is still useful when launching VMs
from images for testing, eg.

lxc launch -p default -p ci-rootnode --vm images:debian/10/cloud/amd64

Without disabling secureboot, extra steps are required to load any
built kernel modules.

jjb: Stop using jgit for lttng-tools jobs

The CI master and the Debian workers are using a more recent
libcurl3-gnutls which doesn't seem to suffer from the same issues when
fetching tags from some of the gerrit repos.

jjb: coverity: fix for curl 8.4

We upgraded curl to work around a git clone issue but this new version
doesn't support combining '--form' or '--data' with '--continue-at'.
Remove the resume support that was added when the Coverity download
server was flaky, they seem to have fixed the issue on their side.

ansible: Install libcurl3-gnutls from bookworm-backports

In the CI builds, we're seeing an issue where certain projects hang
and fail to checkout the gerrit refs.

Eg. ```
git init .
git fetch --tags --force --progress -- \
  https://review.lttng.org/babeltrace \
  +refs/heads/*:refs/remotes/origin/*
git fetch --tags --force --progress -- \
  https://review.lttng.org/babeltrace \
  refs/changes/*:refs/changes/*
```

Not all repositories are affected. There seems to be some type of
content in the gerrit repository that triggers the issue.
After some testing, the version of libcurl3-gnutls available in
bookworm-backports (8.4.0-2~bpo12+1) doesn't seem to be affected
while the version in Debian bookworm (7.88.1-10+deb12u4) fails.

Fetches via SSH are not affected.
