audit: log AUDIT_TIME_* records only from rules

BugLink: https://bugs.launchpad.net/bugs/1969110
[ Upstream commit 272ceeaea355214b301530e262a0df8600bfca95 ]

AUDIT_TIME_* events are generated when there are syscall rules present
that are not related to time keeping.  This will produce noisy log
entries that could flood the logs and hide events we really care about.

Rather than immediately produce the AUDIT_TIME_* records, store the data
in the context and log it at syscall exit time respecting the filter
rules.

Note: This eats the audit_buffer, unlike any others in show_special().

Please see https://bugzilla.redhat.com/show_bug.cgi?id=1991919

Fixes: 7e8eda734d30 ("ntp: Audit NTP parameters adjustment")
Fixes: 2d87a0674bd6 ("timekeeping: Audit clock adjustments")
