I suggest fetching database updates when performing the filesearch, just
like `guix size` does.

The induced cost would be little in my opinion.  A compressed database
for a whole generation is below 10 MiB.  This operation would need to be
done only once per Guix generation.  If we are a bit smart with timestamping
and only send a diff, it could even be much, much smaller.

I think this is a bit beyond the scope of this patch set.  I'd rather
focus on files exclusively for now and proceed one step at a time :)

Cheers!
