thread: use pthread_cleanup_{push,pop}
Each xthr_create wraps the passed in user function in hopes of executing
code after the function returns to clean up some libjeffpc-internal
thread-local state. This needs to happen even if the thread called
pthread_exit.
The pthread_cleanup_{push,pop} functions are the POSIX-provided way to run
such cleanup code.
