Fix mod_wsgi python path

The error was

    mod_wsgi (pid=31466): Target WSGI script '/opt/manoseimas/app/bin/django.wsgi' cannot be loaded as Python module.
    mod_wsgi (pid=31466): Exception occurred processing WSGI script '/opt/manoseimas/app/bin/django.wsgi'.

And this was happening despite

  '/opt/manoseimas/app/eggs/zope.interface-4.1.3-py2.7-linux-x86_64.egg',

appearing in sys.path before

  '/usr/lib/python2.7/dist-packages',

which contains zope/inteface/... for zope.interface 4.0.5.  Maybe the
.pth file was messing things up, I don't know.

See https://github.com/ManoSeimas/manoseimas.lt/pull/121 for some
details about other (failed) attempts to fix this.
