Dalton Hubble de6f27e119 Update FCOS iPXE initrd and kernel arg settings
* Add initrd=main kernel argument for UEFI
* Switch to using the coreos.live.rootfs_url kernel argument
instead of passing the rootfs as an appended initrd
* Remove coreos.inst.image_url kernel argument since coreos-installer
now defaults to installing from the embedded live system
* Remove rd.neednet=1 and dhcp=ip kernel args that aren't needed
* Remove serial console kernel args by default (these can be
added via var.kernel_args if needed)

Rel:
* https://github.com/poseidon/matchbox/pull/972 (thank you @bgilbert)
* https://github.com/poseidon/matchbox/pull/978
