Building and caching old Guix derivations for a faster time machine

Hi Guix, to me the biggest downside of using “guix time-machine” is that it has to do a lot of boring work before the interesting work begins. The boring work includes building Guix derivations for the given channels, most of which have long been collected as garbage on ci.guix.gnu.org. It would
