Fix BOOST_LIB_NAME for Python 3

jakirkham · stefanseefeld · commit 90829714cc60 · 2017-06-12T09:32:31.000-04:00
This was reusing the Python 2 name on Python 3, which is incorrect since
the Python 3 library for Boost.Python now has a `3` in it. Hence this
checks against the Python version and defines this correctly.
