Rust bindings: Use CARGO_MANIFEST_DIR in build.rs

When a rust crate uses the boringssl rust bindings like:

```Cargo.toml
[dependencies]
bssl-sys = { path = "./third_party/boringssl/build/rust" }
```

The working directory of `build.rs` is set to the the crate's
working directory so "." and ".." aren't relative to the bindings'
directory. Use CARGO_MANIFEST_DIR to specify link search paths.
