  hurd: Fix getExecutablePath build
  
  3939a8bf93e27 ("GNU/Hurd: Add getExecutablePath support") added using
  /proc/self/exe for GNU/Hurd but missed adding the required imports for

  Fix the OS string encoding for GNU/Hurd
  
  Following https://github.com/haskell/cabal/pull/9434/files , and as seen
  in the various gnu_HOST_OS usages in the source code, it is expected that
  GNU/Hurd is advertised as "gnu", like the autotools do.

  Ignore Windows CI tool directories in Git
  
  Otherwise, we see thousands of changes in `git status` which is very
  confusing to work with.
