virt: vbox: Add support for the new VBG_IOCTL_ACQUIRE_GUEST_CAPABILITIES ioctl
Add support for the new VBG_IOCTL_ACQUIRE_GUEST_CAPABILITIES ioctl, this
is necessary for automatic resizing of the guest resolution to match the
VM-window size to work with the new VMSVGA virtual GPU which is now the
new default in VirtualBox.
