nptl: Remove futex_supports_exact_relative_timeouts
The only implementation of futex_supports_exact_relative_timeouts always
returns true. Let's remove it and all its callers.
* nptl/pthread_cond_wait.c: (__pthread_cond_clockwait): Remove code
that is only useful if futex_supports_exact_relative_timeouts ()
returns false.
* nptl/pthread_condattr_setclock.c: (pthread_condattr_setclock):
Likewise.
* sysdeps/nptl/futex-internal.h: Remove comment about relative
timeouts potentially being imprecise since it's no longer true.
Remove declaration of futex_supports_exact_relative_timeouts.
* sysdeps/unix/sysv/linux/futex-internal.h: Remove implementation
of futex_supports_exact_relative_timeouts.
