rules: Drop architecture and build-date from required container l…

…abels

(OCI/Docker) containers have a long history, and Red Hat was there in the early days, before things were standardized as OCI even - and especially before things like manifest lists and also the standard annotation keys: https://github.com/opencontainers/image-spec/blob/main/annotations.md#pre-defined-annotation-keys

There are two labels this policy requires that duplicate standard metadata.

- `architecture`: This is already handled via manifest listing and is part of the config
- `build-date`: There's a standard `Created` field

As these are basically legacy from old Red Hat build systems we are just cargo culting forward for as far as I know no good reason, let's stop doing that.
