scripts/build-bpf.sh: Move contract binaries to target/pyth/{solana|pythnet} (#380)

* scripts: Move contract binaries to target/pyth/{solana|pythnet}

This change attempts to provide both contract flavors as a result of
the Docker build. Making both available will help with completing
deployment to both environments.

* check-size.sh: Revert extra arg; rearrange build-bpf.sh instead
