virt: vbox: Add a few new vmmdev request types to the userspace whitelist

Upstream VirtualBox has defined and is using a few new request types for
vmmdev requests passed through /dev/vboxguest to the hypervisor.

Add the defines for these to vbox_vmmdev_types.h and add add them to the
whitelists of vmmdev requests which userspace is allowed to make.
