pythonPackages.django_1_10: 1.10.4 -> 1.10.5

[lsix]

See https://docs.djangoproject.com/en/1.10/releases/1.10.5/ for release
notes.

Motivation for this change

django_guardian fails to build both before and after the update. I’ll look into that ASAP fix it.

The 1.10 series is part of 16.09, I think this update should be backported.
