From: Olivier Dion <olivier-d...@proton.me>
If `join-thread' timeout, the thread mutex is not unlocked,
resulting in deadlock to the next call to it or deadlock of the
thread itself when it terminates.
Thus, always unlock the mutex.
Fix: #55356
* module/ice-9/threads.scm (join-thread): Always unlock thread mutex.
