build_packages: Rebuild only on new revisions
rebuild-if-unbuilt is too aggressive in triggering source rebuilds of
packages and is tripping the referenced bug when rebuilding a package in
both DEPEND and BDEPEND. Changing this option to only build on revision
bump avoids triggering the bug and overall makes our build less eager
to recompile packages from source.
