So far, we determined this based on stdenv.is64bit, but there are cases
where you want to run/build a 32bit program on a 64 bit Windows.
This is now possible, by passing windowsImage.arch = "i686" | "x86_64"
to runInWindowsVM. Based an what was passed, the corresponding Cygwin
packages and setup.exe are bootstrapped.

Another very annoying part. Unfortunately, the only option we might have
here is to include it in nixpkgs or maybe make a fixed Hash on the
result of the closure fetcher.

As the official Cygwin setup binary download doesn't come in snapshots
or even versioned, the fetchurl of setup.exe will frequently fail, which
in turn will annoy us as hell (or at least me).
One warning though: The fetchurl is currently broken and the cross-build
might not work yet for example on mingw32 (mingw-w64 branch on its way),
but the upstream URL has already changed and the new version contains a
bug (not yet tracked down) which breaks our Windows bootstrap process.
So to conclude: If it's already broken, make it at least "less broken".
"Not broken" is coming soon with the merge of the mingw-w64 branch.

Also update 64bit setup.ini and check whether we have a 64 bit stdenv in
order to choose the proper Cygwin version. Otherwise we now have the
setup.ini for 32bit available as well.

So far, the VMs have always been using the native architecture, because
it was reimporting <nixpkgs> several times. Now, we propagate a list of
packages down to all sub-imports, which not only makes clearer which
dependencies a part actually has, but also will make it easier in case
we want to refactor those parts to use callPackage.

This is kinda stupid to do every little time the file is automatically
regenerated upstream. But let's see how often that happens and whether
it will become a major annoyance or not, and if yes, we might be forced
to include it in our source tree.

At least the largest portion of the installer, because in the end we
don't want the installer to *actually* save the state but only prepare
the base image.
