VirtualBox 6.0.x has a new feature where the guest kernel driver passes info about the origin of the request (e.g. userspace or kernelspace) to the hypervisor.
If we do not pass this information then when running the 6.0.x userspace guest-additions tools on a 6.0.x host, some requests will get denied with a VERR_VERSION_MISMATCH error, breaking vboxservice.service and the mounting of shared folders marked to be auto-mounted.
This commit implements passing the requestor info to the host, fixing this.

This feels like support for a "new feature", so why would this need to go to older kernels?
It's not our fault that vb implemented a non-backwards-compatible change for their new release, right? So why should we be forced to add new features to stable kernels?
I have no problem to add this for 5.2, but not for older stuff.
