Use debian-base instead of distroless for conformance image

Browse Source 
The `diff` binary (required by the `kubectl diff` e2e test) gets
statically or dynamically linked based on the used glibc version. We
cannot really predict that behavior for the various platforms of
debian-base and therefore cannot copy the binary around. This means that
distroless is not a great choice for the conformance image unless we
stop relying on `diff`.

This means we now switch back to `debian-base` for the conformance image
to simplify the build process and reduce the amount of moving parts.
