fix typo in error message when failing to find Python 2 install dir

32466ecc452102a1fc84f4331c0ed099da4e7edc replicated the unified Python bindings
support into Python 2 and Python 3 cases. However, it incorrectly used the
Python 3 variable in this error message instead of the Python 2 variable.
Related to #1992.
