When building the install trees, lorax doesn't follow Provides,
so even though grub2-pc, grub2-ppc64 etc. Provide grub2 and
grub2-efi-x64, grub2-efi-ia32 etc. Provide grub2-efi, they
don't get installed, and that stops installs from working.
Although it's messy, we'll just have to list all the archful
package names like this.
A number of the system-config packages have been retired, dhclient has long been
renamed to dhcp-client, and a few other packages in groups have been retired so
remove them from the lists.
