Subject: os/inputthread: Force unlock when stopping thread.

The inputthread is kept locked all the time while X server's VT is not active.
If the X server is terminated while not active, it will be stuck forever in
InputThreadFini waiting for the thread to join, but it wouldn't because it is
locked.
