ebtables-translate: Fix segfault while parsing extension options

Previous review of match/target lookup did not consider
xtables-eb-translate.c which contains the same code. Fix parsing of
target/match arguments there as well by introducing
ebt_command_default() which consolidates the previously duplicated code.

One notable quirk in comparison to the similar xtables code: Since
ebtables allows for negations in ugly places (e.g. '--arp-opcode ! 1'),
ebt_check_inverse2() has to be called first.
