test(xcat-core): the Ubuntu ppc64el netboot image has no dig

Browse Source 
genimage stops with "Failed to find usr/bin/dig in
/install/netboot/ubuntu24.04.4/ppc64el/compute/rootimg" and returns 2, so
packimage writes no initrd.gz and nodeset reports "Did you run genimage
before running packimg?". The diskless compute node never boots.

xCAT-server/share/xcat/netboot/ubuntu ships a package list for ppc64el on
20.04 and on 26.04 only. imgutils::get_profile_def_filename finds no
ppc64el list for 22.04 or 24.04 and falls back to compute.pkglist, which
installs no dig. mkinitrd copies usr/bin/dig into the initrd and
find_rootimg_file calls xdie when the file is absent.

The test reads the four ppc64el package lists the pipeline provisions and
asserts each one installs dig, a kernel and nfs-common. It fails on 22.04
and 24.04 and passes on 20.04 and 26.04.

Evidence: reg_linux_diskless_installation_flat on ubuntu-24-ppc64le-devel
in xcat-core-devel-ubuntu-cd build 120, xcattest.log.20260911175800 on
xcat25-mn.
