The 'fault' subtest submits an exec with a bogus batch address. The
kernel nacks the unresolvable pagefault, which the GuC escalates to a
memory CAT error and engine reset. The resulting 'CAT error' dmesg
messages are expected, not a real failure.

Emit an ignore-dmesg regex to suppress them in CI. It matches both
'Memory CAT error reported by GuC!' and 'Engine memory CAT error'
messages.
