jjb: lttng-tools: fix dev_review_*_root_linuxbuild jobs

These jobs inherited the default wrappers for lttng-tools, including the
proccleaner which doesn't work for 'root' builds as it tries to kill all
processes owned by root that are not started by the jenkins agent before
starting the build.

Set the same custom wrappers as the other 'root' builds.
