util: Don't use rx-internal locking macros
The MUTEX_INIT, MUTEX_ENTER, MUTEX_EXIT and MUTEX_DESTROY macros
are intended for RX internal use only (they're an abstraction
interface so that the same locking code can be used in userspace and
in the kernel). They aren't appropriate for general purpose use.
Just use pthread calls directly for the serverLog locks.
