Fix python sync server on Chrome OS
Fix python sync server on Chrome OS

Bug 58522 was logged because bringing up the python sync server on Mac
failed due to a mismatch in the path to the protobuf files. We recently
noticed the same issue on our Chrome OS autotest runs as well.

This patch modifies the workaround checked in with
http://src.chromium.org/viewvc/chrome?view=rev&revision=62335 so that it
applies to Chrome OS as well.
