Subject: [PATCH 2/2] Add libz-sys to rustc-workspace-hack.

https://github.com/alexcrichton/curl-rust/pull/351 changed
curl-rust to no longer enable the default features of libz-sys.
Because rustfmt includes rustc-workspace-hack with the
rustc-workspace-hack/all-static feature (sometimes), it ends up building
libz-sys without the default features. This causes a duplicate
with other packages (like rls) which enable the default
features.
