nativesdk/sdk: Update sdk dummy providers

When we migrated rpm v5 -> v4, we lost the ability to drop "per file"
dependencies from the rpm backend for things like "/bin/bash" and
"/usr/bin/env" which meant the sdks were becomming 'bloated'.

This restores the functionality using a dummy package, similarly to
the way the buildtools perl issue was addressed. It also removes
the non-functional old code so as not to confuse people in future.

I ran into this problem trying to filter dependencies to only rpms
a build directly depends upon and it turns out we have some determinism issues
in this area so this is something key to fix.
