nptl: Fix PTHREAD_PRIO_PROTECT timed lock
The 878fe624d4 changed lll_futex_timed_wait, which expects a relative
timeout, with a __futex_abstimed_wait64, which expects an absolute
timeout.  However the code still passes a relative timeout.

Also, the PTHREAD_PRIO_PROTECT support for clocks different than
CLOCK_REALTIME was broken since the inclusion of
pthread_mutex_clocklock (9d20e22e46) since lll_futex_timed_wait
always use CLOCK_REALTIME.

This patch fixes by removing the relative time calculation.  It
also adds some xtests that tests both thread and inter-process
usage.

Checked on x86_64-linux-gnu.
