resources: Fixed square build documentation
Square needs to be built via the `gcn-gpu` docker image. Previously the
README.md falsely claimed it could be built by installing the ROCM
compiler.
This commit also cleans-up the `src/square/Makefile` and added the
`src/square/bin` directory to `src/square/.gitignore`.
