rootfs_rpm.bbclass: Add additional system configuration to RPM space

The additional configuration should have been there from the beginning.  The
purpose of these config files is to have a consistent Berkeley DB configuration
even if the underlying RPM version changes -- or the RPM macros change.

This likely would not cause any problems until we attempted an upgrade of
either BDB or RPM.
