test(xcat-core): nodeset refuses an Ubuntu POWER live image it can boot

Browse Source 
reg_linux_diskfull_installation_flat fails on every ppc64le cell of
xcat-core-devel-ubuntu-cd. nodeset stops before it writes a grub2 entry
(build #119, ubuntu-24-ppc64le-devel):

    xcat25-cn: The network boot initrd.gz is not found in
    /install/ubuntu24.04.4/ppc64el/install/netboot.

The Ubuntu ppc64el live-server ISO carries no netboot tree. It keeps the
installer kernel and initrd under casper: 22.04 and 24.04 ship hwe-vmlinux and
hwe-initrd beside vmlinux and initrd, 26.04 ships the release pair only.
%INSTALL_BOOT_FILES describes that layout for x86 and not for POWER, and
mkinstall carries a second, POWER-only precondition on
install/netboot/initrd.gz that no live image satisfies.

The new cases resolve the POWER casper layouts, and ask a single routine
whether media is bootable. They fail now.
