kjellander@webrtc.org ccb52c2961 Improve error handling for barcode_tools
These changes make the execution abort earlier on an error (like a tool is not found) and makes it easier to figure out what's wrong.

Made build_zxing.py executable.

BUG=None
TEST=Local runs of the PyAuto test src/chrome/test/functional/webrtc_video_quality.py in Chromium.
