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The `hadrian/doc/windows.md` file has falled out of date.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

 These are currently not the

 [official GHC building instructions](https://ghc.haskell.org/trac/ghc/wiki/Building/Preparation/Windows),
