cargo-update-recipe-crates: Don't fail for partially empty Cargo.lock

Do not fail if only some Cargo.lock files are empty. Only fail, if there
are absolutely no dependencies found in any Cargo.lock.

This fixes the following error message, which would occur with "bitbake
-c update_crates python3-orjson":
