Fix: build failures when `--without-lttng-ust`

The `--without-lttng-ust` configure option makes the build to fail due
to 2 bugs
1. Missing object file for session unit tests causes the following errors:

2. An extra colon at the end of the `trace_ust_track_id()` stub
function gives this error:
    CC       utils.o
  In file included from ust-app.h:26:0,
                   from lttng-sessiond.h:31,

                     ^~~~~~~~~~~~~~~~~~
  Makefile:729: recipe for target 'utils.o' failed

Both bugs are trivial to fix.
