Rust 1.67 was announced[0].
Update the nix sources to be on par with the latest rustc version.
This required fixes to clippy warnings for using variable
interpolation for format strings.
There was also an advisory error related to libgit2-sys[1], which is
transitively depended on via git2. The fix is included in the 0.16.1
version of git2.

We add tests for ODB functionality, as well as a new `TreeBuilder`
Struct to make building git trees easier (see below).
The `git2::TreeBuilder` can be a pain to use since it has a lifetime
that is tied to the `git2::Repository`. This was causing issues when
trying to write generators for property tests.
Instead, define a custom TreeBuilder which is a defunctionalised list
operations that represent the `insert` and `remove` methods on
`git2::TreeBuilder`.
The implementation of writing a tree then becomes converting the
custom `TreeBuilder` into a `git2::TreeBuilder`.
