Use feh only as a fallback if the xserver is actually enabled.
Otherwise feh is installed even though no xserver is available.
vm/windows: Allow to specify a different arch.

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.

zfs: Fix libblkid detection (backport from upstream)

This fixes issues with importing ZFS pools, such as when the ZFS device is a
partition that covers the end of the disk.

See: https://github.com/zfsonlinux/zfs/issues/1684
zfs: Don't look for devices only in /dev

If we don't give out a directory to 'zpool import', it will use libblkid
to automatically find all existing ZFS devices.
zfs: Fix minor filesystem corruption with gcc 4.8
