posix-timers: Expand timer_[re]arm() callbacks with a boolean return value

Browse source

In order to catch expiry times which are already in the past the
timer_arm() and timer_rearm() callbacks need to be able to report back to
the caller whether the timer has been queued or not.

Change the function signature and let all implementations return true for
now. While at it simplify posix_cpu_timer_rearm().

No functional change intended.
