Adhemerval Zanella b769b0a2cb linux: Only use 64-bit syscall if required for internal futex 
For !__ASSUME_TIME64_SYSCALLS there is no need to issue a 64-bit syscall
if the provided timeout fits in a 32-bit one.  The 64-bit usage should
be rare since the timeout is a relative one.

Checked on i686-linux-gnu on a 4.15 kernel and on a 5.11 kernel
(with and without --enable-kernel=5.1) and on x86_64-linux-gnu.

Florian Weimer b5be9ae77e nptl: Move futex-internal into libc 
This moves  __futex_abstimed_wait64 and
__futex_abstimed_wait_cancelable64 and exports these functions as
GLIBC_PRIVATE.
