MDEV-11221 - main.events_restart failed in bb

Browse Source 
This is an addition to original fix. Buildbot revealed another sporadic failure
in perfschema.threads_mysql test. Tests relies on data stored in
performance_schema.threads, while performing waits on
information_schema.processlist. These tables are not updated synchronously.

Fixed by performing waits on performance_schema.threads instead.
