src: get rid of EINTR handling for nft_netlink()

The only remaining caller that needs this is netlink_dump_ruleset(), that is
used to export the ruleset using markup representation. We can remove it and
handle this from do_command_export() now that we have a centralized point to
build up the object cache.
