[PATCH v2 1/5] libgitpub: move to separate contrib/ directory

[Josh Steadmon <steadmon@google.com>]

For Cargo packaging purposes, it is better for any dependencies built with Git's
Makefile to live outside the libgit-{sys,rs} crates. This, plus some future
changes to the crates, will allow `cargo package` to treat all of the non-Rust
source as a separate tree apart from the Cargo-managed inputs.
