branch, tag: use porcelain output

Call ref-filter's setup_ref_filter_porcelain_msg() to enable
translated messages for the %(upstream:tack) atom. Although branch.c
doesn't currently use ref-filter's printing API's, this will ensure
that when it does in the future patches, we do not need to worry about
translation.
