Fix instability in 031_recovery_conflict.pl.

Where the test wants a VACUUM command to generate WAL that would
conflict with a session on the standby, it could transiently fail to do
so if it couldn't acquire a cleanup lock conditionally at that moment on
the primary.  VACUUM FREEZE will wait, so use that instead.

No back-patch for now, but that will be needed if/when the test is
re-enabled in back-branches.
