[PATCH i-g-t v3 0/2] Ignore more warns in xe_wedged tests

[Kamil Konieczny]

It turns out that there are more drm warnings which should be ignored
by igt_runner. Tests succeeds but later on when generating results
runner turns it into a failure.

v2: corrected and added more regex-es, move '|' to begin of split
  strings for better reading, corrected name in Cc and added r-b
v3: corrected drmtest logic for opening cards, improved assert
  logic for xe unbind (Kamil)
