Alexander Shishkin 339bc41835 perf/ring_buffer: Fix AUX record suppression
The following commit:

  1627314fb5 ("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.
