xtables-restore: Use xt_params->program_name

Instead of setting newargv[0] to argv[0]'s value, just use whatever
xt_params->program_name contains. The latter is arbitrarily defined, but
may still be more correct than real argv[0] which may simply be for
instance xtables-nft-multi. Either way, there is no practical
significance since newargv[0] is used exclusively in debug output.
