metadata: handle ABI version rebuild tracking for transient dependencies

Extend the packageauxvars database to keep a list of possible package
dependencies for each provider, then utilize this information in buildroot
to resolve the ABI version dependencies of dependent packages up to five
levels deep.

This should properly trigger rebuilds for packages indirectly depending
on other packages whose ABI_VERSION changed.
