package_rpm: Fix solverdb generation

The RPM solverdb was potentially being generated multiple times.
Fix this by ensuring we only process each directory once.

Also correct an issue where the solution did not necessarily follow
the preferred architecture ordering, reverse the default Poky ordering
so that preferred is listed first.
