Once change 2342 is in place (running first boot scripts exported from
packages), see https://review.haiku-os.org/c/haiku/+/2342,
remove data/system/boot/post_install/add_catalog_entry_attributes.sh
and related support infrastructure (magic files, launch_roster entries).
The work this script did can in fact be done at image creation time
instead of at first boot.
