    Update upstream repo url for `haskeline`

    [hackage:haskeline] has now an official GitHub repo at
    https://github.com/judah/haskeline.git

    Consequently, there remain only 3 repos which are Darcs hosted
    (and thus still require darcs2git mirroring), namely
    [hackage:time], [hackage:terminfo], and [hackage:transformers].
