arptables-nft: remove ARPT_INV flags usage
ARPT_ and IPT_INV flags are not interchangeable, e.g.:
define IPT_INV_SRCDEVADDR 0x0080
define ARPT_INV_SRCDEVADDR 0x0010
as these flags can be tested by libarp_foo.so such checks can yield
incorrect results.
Because arptables-nft uses existing code, e.g. xt_mark, it makes
sense to unify this completely by converting the last users of
ARPT_INV_ constants.
Note that arptables-legacy does not do run-time module loading via
dlopen(). Functionaliy implemented by "extensions" in the
arptables-legacy git tree are built-in, so this doesn't break
arptables-legacy binaries.
Fixes: 44457c080590 ("xtables-arp: Don't use ARPT_INV_*")
