Reduce the scope of the proctree_lock. If several processes cause
continuous calls to the uprintf(9), the proctree_lock could be
shared-locked for indefinite amount of time, starving exclusive
requests. Since proctree_lock is needed for fork() and exit(), this
effectively stops the machine.
While there, do the similar reduction for tprintf(9).
