prepare-tmpinfo runs on every build and calls package-metadata.pl
three times, although tmp/.packageinfo usually did not change. It also
writes tmp/.config-feeds.in on every build: the check against
tmp/.packageauxvars never passes, as that file is written again later
in the same recipe.
Generate the package metadata files only if tmp/.packageinfo or the
scripts are newer, and replace tmp/.config-feeds.in only if its content
changed.
