Add extra data from fedora RPMs

See https://koji.fedoraproject.org/koji/buildinfo?buildID=2390057
Here the extra tag seems to contains important source and git details using a vcs_url format in a JSON-like data:
> Extra {'source': {'original_url': 'git+https://src.fedoraproject.org/rpms/thunar-sendto-clamtk.git#5a3f8e92b45f46b464e6924c79d4bf3e11bb1f0e'}}

This is worthy to be investigated. It is also in the Source tag.
