[PULL 05/31] tests/functional: skip vulkan tests with nVidia

["Alex Bennée" <alex.bennee@linaro.org>]

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

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.
