Prevent an early load of the Astribank (xpp) drivers at initrd time, as
they require some files from the root filesystem.
This installs a file in the dracut configuration directory that will
take effect the next time dracut generates an initrd image.
This installs an configuration file for dracut which is ignored if
dracut is not installed and is a no-op if xpp_usb is not loaded on your
system.
