Subject: [PATCH] vimPlugins.LanguageClient-neovim: fix Rust build

The build issue was caused by issue in traitobject crate
https://github.com/reem/rust-traitobject/issues/8 and was fixed in
0.1.1 version. Since LanguageClient-neovim doesn't get much attention,
patch Cargo.lock here to use the newer version of traitobject crate.

Fixes https://github.com/NixOS/nixpkgs/issues/424400
