We don't want to check against the current version known to the host
system, because that will be incorrect in a wide variety of situations,
including:
- the build host hasn't done a full system upgrade yet
- we're building against staging, and want to see the delta between
  different staging versions
- we're building against extra, but the host runs testing which carries
  changes we don't want to visualize right now
- the chroot has a configured database not available to the host, and
  the package is only available there

Essentially, it's rarely 100% correct to run checkpkg on the host, but
we already have a database we *know* is correct, and that is the one we
just built the package against. So let's use that.

This also fixes a bug in the current logic, where in order to try
downloading fresh databases, we work in a non-cached temporary working
database to download the package files, but then let checkpkg default to
comparing packages in the system database. Since we are explicitly
trying to compare against packages that differ from the host's pacman
database, we need to pass the package files as options to checkpkg,
using the additional modes added in commit c14338c0fe71a74f5e56b4f3af7c548fe0928e15
