This is achieved using "jobs" from packit-as-a-service, more
specifically the propose_downstream job. Furthermore
sync_from_downstream job is configured to keep the spec file
synchronized and prevent merge conflicts for new releases.
Also a small change in Makefile was necessary as it does not reflect the
current state of the spec file in Fedora dist-git (tarball name is
different). The spec file itself is not modified in this commit, because
it will be synchronized automatically using Packit.
packit is a service for continous delivery into Fedora repositories. It
should help us synchronize upstream repository on Github with downstream
repository on src.fedoraproject.org.
