While running the new GPU tests it was noted that the proprietary
nVidia driver barfed when run under the sanitiser:
2025-02-20 11:13:08,226: [11:13:07.782] Output 'headless' attempts
EOTF mode SDR and colorimetry mode default.
2025-02-20 11:13:08,227: [11:13:07.784] Output 'headless' using color
profile: stock sRGB color profile
and that's the last thing it outputs.
The sanitizer reports that when the framework sends the SIGTERM
because of the timeout we get a write to a NULL pointer (but
interesting not this time in an atexit callback):
UndefinedBehaviorSanitizer:DEADLYSIGNAL
==471863==ERROR: UndefinedBehaviorSanitizer: SEGV on unknown address

The #dri-devel channel confirmed:
<digetx> stsquad: nv driver is known to not work with venus, don't use
it for testing
So lets skip running the test to avoid known failures.
