Compiling the kernel modules on Linux 4.12 fails, so I've included an
upstream patch from:
https://www.virtualbox.org/changeset/66927/vbox
The patch is applied against the guest additions as well, where we need
to transform the patch a bit so that we get CR LF line endings (DOS
format), which is what is the case for the guest additions ISO.
I've tested this with all the subtests of the "virtualbox" NixOS VM
tests and they all succeed on x86_64-linux.
