Title: EMRJobRunner handles lack of interpreter

HadoopJobRunner should require a similar change. For the moment, I've only verified this change by hand and it only works on UNIX (like the LocalJobRunner version).

Things we still need:
* Hadoop runner needs to match behavior
* Document behavior
* Use `--no-interpreter` instead of checking UNIX-specific flags

Do you want anything else besides those 3 things before merging this feature?
