David Ostrovsky f2099fa403 merge_jars.py: Make the code work on Python 3
So far the gerrit build tool chain works as expected on Python 3. The
only problems that we are running into in merge_jars.py:

* ZipFile.read is returning byte and not string
* dict.iteritems() was removed in Python 3

Luckily, those problems can be easily rectified and code can be adjusted
to be compatible with both Python version 2 and 3.

Bug: Issue 7002
