[glibmm] threadpool example: Use Mutex instead of StaticMutex.

[Murray Cumming <murrayc src gnome org>]

commit acf84955b9a86597e4675a0edc0848851ecafba7
Author: Murray Cumming <murrayc murrayc com>
Date:   Wed Oct 26 22:27:48 2011 +0200

    threadpool example: Use Mutex instead of StaticMutex.
    
    * examples/thread/threadpool.cc: The advantage of StaticMutex was that
    it would silently do nothing if threads were not initialized. That
    was never a useful distinction in this example anyway.
    Also remove the deprecated thread_init() call.
    * glib/src/thread.ccg: Mutex: Add a TODO about not using the deprecated
    API.
