[Intel-gfx] [igt v2] igt/kms_psr_sink_crc: Fix the bug in psr_drrs subtest

[Radhakrishna Sripada]

The substring to be matched is "DRRS Supported: Yes" and not
"DRRS Support: No". The kernel prints the DRRS status for all active
CRTC's. Matching for No support gives a false positive when multiple
CRTC's are active.
