fix(rust): fetch CARGO_MANIFEST_DIR at runtime in build script

Browse source 
The `CARGO_MANIFEST_DIR` environment variable should be accessed by
`build.rs` at run time rather than compile time. This was for example
causing issues when importing `tree-sitter` via
[`rules_rust`](https://github.com/bazelbuild/rules_rust) in bazel,
where compilation and running happen in separate environments.
