posix-timers: Introduce clockid_to_kclock()

New function to find the kclock for a given clockid.

Returns a pointer to clock_posix_cpu if clockid < 0. If clockid >=
MAXCLOCK or if the clock_getres pointer is not set it returns
NULL. For valid clocks it returns a pointer to the matching
posix_clock.
