rtems: Use allocator mutex for timer server

The allocator mutex is recursive and already used for the task creation
in rtems_timer_initiate_server().  Just use this mutex instead of the
once mutex to serialize the initialization.  This avoids a dependency on
condition variables which are not used here.
