nixos: Add VM test for VirtualBox.
Currently it pretty much tests starting up virtual machines and just shutting down afterwards, but for both VBoxManage and the VirtualBox GUI. This helps catching errors in hardened mode, however we still need to test whether networking works the way intended (and I fear that this is broken at the moment). The VirtualBox VM is _not_ using hardware virtualization support (thus we use system = "i686-linux", because x86_64 has no emulation support), because we're already within a qemu VM, which means it's going to be slow as hell (that's why I've written own subs just for testing startup/shutdown/whatnot with respective timeouts).
