As I assume you saw, there is nothing "optional" when using the
cargo-build-system. For nettle-sys and nettle-src I suggest looking at
rust-openssl-sys-no-vendor.patch which I modified from Debian. It takes
care of pretending openssl-sys also provides openssl-src.

That could probably move to a snippet, or even into the
cargo-build-system. IIRC there are only 3 patterns like that which
appear multiple times, and they're only relevant when building that
actual crate, not when it's "just a dependency".
