Multiple small fixes for the vagrant environment

- Drop the hardcoded pagure config in ~ since we actually use the
  one in /etc/pagure.

- Install the new dependency whitenoise that handles the static files
  cf https://pagure.io/pagure/pull-request/4885

- Create the /usr/local/lib/python... folder before trying to create
  a symlinkg in it

- Fix the symlink created in /usr/local/lib/python... so it points
  to the pagure module rather than the git clone (ie one level to
  high)
