Add NEWS entry about 64-bit time_t syscall use on 32-bit targets
This internal change ideally should not affect the public API or ABI, but there is a widespread use of seccomp sandboxes, even on 32-bit targets, that don't handle new Linux syscall usage well, so it's worth mentioning in the NEWS. Co-authored-by: Siddhesh Poyarekar <siddhesh@sourceware.org>
