Ghost 8be7956fc0 fetchFromGitLab: force re-fetch when rev changes (#14)
There are a few instances of `fetchFromGitLab` in the repo, for instance `gtk-doc.src`.

My primary goal when writing this was changing the output derivation following #11. This is doable with a lot less diff in `fetchFromGitLab`, but it's worth asking whether both fetchers should be different and why. I think a lot of the divergence comes from years of random commits rather than from design.
