pid1: load 'qemu_fw_cfg' kmod super early, so that we can import credentials from it

Browse Source 
In one of the next commits we want to add support for importing system
credentials from qemu_fw_cfg, very early during boot. (So that we can
use the credentials therein for generators and even earlier). But that
means udev won#t load these modules for us, we have to load them
manually first.
