When installing the panko-api and panko-common
packages for Ubuntu the path to the wsgi script is
no longer /usr/share/panko-common/app.wsgi but is
now /usr/lib/python2.7/dist-packages/panko/api/app.wsgi
This patch changes that script path. It depends on the
Gnocchi change in order to test this since Gnocchi has
to be fixed in order to run testing. [1]
