libselinux is also broken by time64 for arc

This probably is fixed upstream already as
SELinuxProject/selinux#464 uses
__INO_T_MATCHES_INO64_T, which should correctly evaluate on glibc
architectures whereas the Debian package has a local patch covering x32
only. So this is producing a misbuild for arc as it adds compatibility
that is not needed as arc never had 32bit time_t.
