Currently, rpmautospec.tag_package tags all builds of a package, which can take a long time for packages with a long history (even more so when not operating locally but using the Pagure API for it, one tag at a time).

For our purposes, it's enough to have the respective latest (EVR-wise) build tagged in the repo, we should either do this wholesale, or offer it as an option (to be used by in the process_distgit_cb callback of the rpmautospec_build Koji plugin).
