perf tests: Skip metrics validation if system-wide recording lacks permission

Browse source

The metrics value validation test requires system-wide recording (`-a`),
which can fail on systems without root permissions or where paranoid
levels restrict tracing. Add a check to skip the test if `-a` is not
supported.

Also fix false negatives during validation by updating parse error string
patterns and resolving issues in metric list generation.
