[ltt-dev] [UST PATCH 1/3] Try harder to find a usable lttv in the tests scripts v2

[Yannick Brosseau]

Add many more attempts to auto-detect the path to the lttv executable or
the runlttv script in trace comparison tests.
Also support setting the LTTV env variable to directly set a path the
the lttv executable in addition to the RUNLTTV variable

Changelog:
   Correctly manage multiple traces
