arc4random(3): Use mutex_init, not mutex_unlock, in child post-fork.

Using mutex_unlock may try to wake a thread that doesn't exist in the
child, which could lead to trouble such as crash or deadlock.  But
since the child is single-threaded, it is safe to just reinitialize
the mutex memory anyway.
