The source release tar.gz configures vendored deps, but not .cargo/config

[nipunn1313]

For example cargo-vendor-src-0.1.13.tar.gz from the releases page.

Inside the tar, we have all the source to cargo-vendor itself as well as vendored dependencies. However, if you fetch this tar and do a cargo build, it does not appear to use the vendored deps because .cargo/config is not set in that directory.

Looking at the .travis.yml, I think the pre-deploy step needs to set the .cargo/config.

This crate is now included natively in Cargo as of rust-lang/cargo#6869 and today's nightly Rust. I'm closing all issues in this repository before I archive the repository, but if you're still interested in seeing this issue fixed then please feel free to file an issue with Cargo itself!
