Adhemerval Zanella a3e7aead03 nptl: Replace __futex_clocklock_wait64 with __futex_abstimed_wait64 
For non null timeouts, the __futex_clocklock_wait64 creates an a
relative timeout by subtracting the current time from the input
argument.  The same behavior can be obtained with FUTEX_WAIT_BITSET
without the need to calculate the relative timeout.  Besides consolidate
the code it also avoid the possible relative timeout issues [1].

The __futex_abstimed_wait64 needs also to return EINVAL syscall
errors.

Checked on x86_64-linux-gnu and i686-linux-gnu.
