Instead of trying to change the RPATH in every file under the binary
directories, check that the file is an ELF first.

This means that we don't attempt to change the RPATH on the entire
Python standard library, for example.

Also return early if the directory to iterate doesn't exist.

Retracting this, a chunk is missing.
