Do not load 'dummy-hcd' kernel module

It isn't really needed. It was used to workaround libusb bug (causing
crash when the system does not have any USB controller), but since we
use HVM now which do have some USB controllers it isn't needed anymore.

Also, it is not available in stock Fedora kernels.
