posix-cpu-timers: Do not arm SIGEV_NONE timers

Browse source

There is no point in arming SIGEV_NONE timers as they never deliver a
signal. timer_gettime() is handling the expiry time correctly and that's
all SIGEV_NONE timers care about.

Prevent arming them and remove the expiry handler code which just disarms
them.
