Update Matchbox profile to use initramfs and rootfs images

Browse Source 
* Fedora CoreOS stable (after Oct 6) ships separate initramfs
and rootfs images, used as initrd's
* Update profiles to match the Matchbox examples, which have
already switched to the new profile and to remove the unused
kernel args
* Requires Fedora CoreOS version which ships rootfs images
(e.g. stable 32.20200923.3.0 or later)
