Some filesystems do not support negative c/m/atime timestamps. And for these filesystems, generic/258 will fail. Since there's currently no way to check sb->s_time_min from userspace, this patch adds a new common/rc function _require_negative_timestamps() that will _notrun depending on the $FSTYP variable.
