futex: Remove not used futex_reltimed_wait{_cancelable}
After gai_suspend and aio_suspend conversion to support 64 bit time and hence rewriting the code to use only absolute variants of futex wait functions (i.e. __futex_abstimed_wait64 and __futex_abstimed_wait_cancelable64) futex_reltimed_wait{_cancelable} are not needed anymore and can be removed.
