stdenv/check-meta: Make `checkValidity` only check validity

checkValidity has the responsibility to check if a derivation's attributes are valid.
Previously it also had the overloaded task of creating a subset of meta attributes:
- unfree
- broken
- unsupported
- insecure

Not only is this overloading strange, these attributes were only ever consumed by `commonMeta`.

This change makes checkValidity _only_ check for validity, and removes the creation of any meta attributes from `checkValidity` and moves them to `commonMeta`.

This is technically a breaking change but I don't expect any external nixpkgs consumers to rely on these implementation details.
