testing: bump mips64el cross to bookworm and fix package list

The mips64el cross setup is very broken for bullseye which has now
entered LTS support so is unlikely to be fixed. While we still can't
build the container with all packages for bookworm due to a single
missing dependency that will hopefully get fixed in due course. For
the sake of keeping the CI green we disable the problematic packages
via the lcitool's mappings.yml file.
