[PATCH 2/4] tests/intel/xe_wedged: Fix wedged dmesg ignore regex

[Shuicheng Lin <shuicheng.lin@intel.com>]

The kernel now reports the failed GT reset and the device wedge through
SIGID-based logging:

  SIGID=106 FATAL (-ECANCELED) Tile0: GT0: GT: reset failed
  SIGID=102 FATAL (-EIO) WEDGED: Device declared wedged!

which the existing "reset failed .-ECANCELED" and "declared device ...
as wedged" patterns no longer match, so these expected errors are
reported as dmesg-warn. Add patterns for the new messages.

Also fix the CAT error pattern. igt_emit_ignore_dmesg_regex() passes the
regex to igt_runner through /dev/kmsg, which escapes '\' as "\x5c", so
"\[" no longer matches a literal '['. The pattern also lacked the space
before "class=". Use bracket expressions and add the missing space.
