perf/ring_buffer: Fix AUX record suppression
The following commit:
1627314fb54a33e ("perf: Suppress AUX/OVERWRITE records")
has an unintended side-effect of also suppressing all AUX records with no flags
and non-zero size, so all the regular records in the full trace mode.
This breaks some use cases for people.
Fix this by restoring "regular" AUX records.
