This seems to be Apple's doing.  AFAICT, 10.12 is shipping with this
Extras.pth file in /Library/Python/2.7; it's something new.  And,
unfortunately, due to https://bugs.python.org/issue4865, the
site-packages directory for the system Python 2.7 is included in
sys.path along with the non-system framework Python site-packages.
