- Add support for files to VBoxManage createrawvmdk. Currently
it only supports character devices so it failes like this:

VBoxManage internalcommands createrawvmdk -filename test.vmdk -rawdisk /vbox/HardDisks/test.img
VBoxManage: error: File '/vbox/HardDisks/test.img' is no character device
VBoxManage: error: The raw disk vmdk file was not created
