osbuild-service-maintenance: Vacuum tables

Browse source 
Call vacuum analyze after each chunk of updates, and dump vacuum stats
at the beginning and end of the db cleanup.

Nulling results can increase size on disk, but calling vacuum analyze
will free up space within the table (not on disk) and reuse the space
for new inserts and updates.
