clone: add tags refspec earlier to fetch refspec

In clone.c we call refspec_ref_prefixes() to copy the fetch refspecs from the `remote->fetch` refspec into `ref_prefixes` of `transport_ls_refs_options`. Afterwards we add the tags prefix `refs/tags/` prefix as well. At a later point, in wanted_peer_refs() we process refs using both `remote->fetch` and `TAG_REFSPEC`. Simplify the code by appending `TAG_REFSPEC` to `remote->fetch` before calling refspec_ref_prefixes(). To be able to do this, we set `option_tags` to 0 when --mirror is given. This is because --mirror mirrors (hence the name) all the refs, including tags and they do not need to be treated separately.
