posix-cpu-timers: Use PF_EXITING to indicate exit
Right now POSIX CPU timers use task::exit_state to check whether a task is
exiting. That works correctly, but exit_state is set later in do_exit() and
too late for allowing to cleanup POSIX timers earlier.
It does not matter in case of exit whether the cutoff is a bit earlier.
