cronolog: update URLs

Original page has gone away, but fossies has the tarball and archive.org
has the homepage.

Fixes #35021.
jigdo: dependency fixes

It complains, loudly, about using db5 and suggests downgrading to db4,
so that’s done here. It also needs wget to be present on the system for
the ` jigdo-lite ` element to function.

Aside those two things, just style changes.
jigdo: add 0.7.3 bottle.
