Fix source file definition and handling

- Use archive name expected by GitLab, then the archive does not contain
  whole commit reference.
- Use standard %forgemeta macros, although some detail neede to be fill
  in – GitLab handling is not detected from URL.
- Fix upstream URL.

Thanks Andreas <asn@redhat.com> for PR#4,
from which half of this fixes originate!

Closes: #4
