ctdb-locking: Set real-time priority for lock helpers
To avoid lock helper starvation when userspace robust mutexes are
enabled.
Commit 6f072f85a138f595494dbec137bcf23d1e666acc removed reset_scheduler(),
to avoid resetting scheduler priority. However, that is not sufficient
because of commit 1be8564e553ce044426dbe7b3987edf514832940, which sets
SCHED_RESET_ON_FORK flag. With SCHED_RESET_ON_FORK, all CTDB child
processes will automatically have normal scheduling priority.
