Hadrian: Update instructions for building on Windows
The `hadrian/doc/windows.md` file has falled out of date. In particular
it still points to the old GitHub repository, and uses incorrect path
to GHC. This patch fixes it.

# Building GHC on Windows
-[](https://ci.appveyor.com/project/snowleopard/hadrian)

+We only assume that `git` and `stack` are installed (see

These are currently not the
