Ensure reporead is protected against simultaneous runs
This adds a bunch of transaction magic and SELECT FOR UPDATE stuff to
reporead to cope with the now-concurrent runs of reporead we get when
invoked from our inotify-based updater. The collision occurs with 'any'
architecture packages as both repo databases contain the new version,
and the updates occur at exactly the same time.
