    Travis: allow user forks
    
    Check for each submodule repository url if the user made its own fork.
    If so, use that. Otherwise, fall back on the one from github.com/ghc.
    
    As suggested by Richard in this mailinglist discussion:
    https://mail.haskell.org/pipermail/ghc-devs/2014-November/007300.html
    
    Documentation is at [wiki:TestingPatches#Travis].
