Subject: [PATCH] Detect if args were passed to image_to_usb, die if they are.

build_image interface now only support arg arguments rather than
flags. This might be confusing for users who might expect something
to happen when they run image_to_usb dev.

BUG=chromium-os:27362
TEST=Tested with/without args.
