[PATCH v1 2/3] posix-cpu-timers: Replace cpu_timer_pid_type with clock_pid_type

[Eric W. Biederman]

Taking a clock and returning a pid_type is a more general and
a superset of taking a timer and returning a pid_type.

Perform this generalization so that future changes may use
this code on clocks as well as timers.
