make posix timer family functions reject itimer timer ids

we provide two sets of similar apis:
* BSD itimer api (setitimer, ITIMER_xxx, and friends)
* posix timer api (timer_create and friends)

for some reason, some of posix timer functions
(namely timer_settime, timer_gettime, timer_getoverrun,
timer_delete) are allowed to operate on timer_id=2,
which actually belongs to the BSD itimer. (ITIMER_PROF)

it seems that it has always been this way since they were
introduced on the nathanw_sa branch in 2001.
10 years later, in 2011, it got a bit worse by the addition
of ITIMER_MONOTONIC, which is also accepted by the posix
timer functions.

as there seems to be no reasons to give the special
treatment to these two itimers, this commit makes the posix
timer functions reject them.
