test(xcat-core): the Ubuntu ppc64le install drops the bootloader package

Browse Source 
The Subiquity apt configuration sets APT::Install-Recommends "false" for every
architecture. On ppc64el the target gets grub-ieee1275 only as a recommended
package of the kernel image, so the setting removes it and curtin fails.

The test renders the apt block for osarch ppc64el, online and offline, and
requires that it does not disable the recommended packages. Both assertions
fail before the fix.

Evidence: reg_linux_diskfull_installation_flat on Ubuntu 24.04 ppc64le,
xcat-core-devel-ubuntu-cd build 122, cluster xcat25. curtin-install.log:
"dpkg-query: package 'grub-ieee1275' is not installed", from
['unshare', '--fork', '--pid', '--mount-proc=/target/proc', '--', 'chroot',
'/target', 'dpkg-reconfigure', 'grub-ieee1275'].
