feat(rust-zerocopy-derive): pin to upstream commit for version 0.8.42

Pin rust-zerocopy-derive to Fedora dist-git commit
079ba44c4ab6757eb34625c8a9483c514cd9c748, bumping the version from
0.8.31 to 0.8.42.

Move rust-zerocopy-derive from inline entry in components.toml
to a dedicated comp.toml to support the upstream-commit pin.
