Bug 1210157 - Use unicode_literals in all mozboot modules r=firefox-build-system-reviewers,mshal

Add unicode_literals to all mozboot module __future__ statements to support
running the modules under Python 3.  Remove comments about unicode_literals and
Python 2.6 support as Python 2.6 is no longer supported in tree.
