ebtables: fix over-eager -o checks on custom chains

Arturo reports ebtables-nft reports an error when -o is
used in custom chains:

-A MYCHAIN -o someif
makes ebtables-nft exit with an error:
"Use -o only in OUTPUT, FORWARD and POSTROUTING chains."

Problem is that all the "-o" checks expect <= NF_BR_POST_ROUTING
to mean "builtin", so -1 mistakenly leads to the checks being active.
