Update the python auto-install on Windows to 2.7.6.

2.7.5 has bug http://bugs.python.org/issue17998 in re package that is affecting
the chromium team so it can't be used. The bug is fixed in 2.7.6.

This update still respects DEPOT_TOOLS_PYTHON_275=0. Since the name doesn't
represent what is being installed, it also respects
DEPOT_TOOLS_PYTHON_27=0.
