Add support for glibc's y2038 APIs in the libc backend. The musl and android targets are not y2038 compatible on 32-bit platforms, however in musl's case, this will be fixed when Rust itself is updated to musl 1.2, and in android's case, this is because android itself does not intend to be y2038-compatible on 32-bit platforms. This strengthen's rustix's y2038 stance to: support y2038 compatibility on platforms which have support for this.
