Update run-bindings-tests per compute_interfaces_info split

This updates r-b-t (currently breaking) following:
Bindings build: split compute_interfaces_info into 2 stages
https://codereview.chromium.org/300273005/

Sorry for breakage!
This wasn't caught earlier because files were renamed, then changed,
so the old bytecode (.pyc) was still being used.
