Fix duplicate src/main.rs discovery (#51)

If a `[[bin]]` for `src/main.rs` is explicitly declared with a different name than the crate the code would previously add two entries to the `bin` field of the `Manifest`. This commit fixes the discovery by only comparing the paths, but not the names of the discovered targets.
