toaster: settings.py , add * to ALLOWED_HOSTS

This backports 7c3a47ed8965c3a3eb90a9a4678d5caedbba6337 to krogoth so that toaster can work with Django (1.8.16).

From the patch to master's message:
As of Django 1.8.16, django is rejecting any HTTP_HOST header that is not on the ALLOWED_HOST list. We often need to reference the toaster server via a fqdn, if we start it via webport=0.0.0.0:8000 for instance, and are hitting the server from a laptop. This change does reduce the protection from a DNS rebinding attack, however, if you are running the toaster server outside a protected network, you need to be using the production instance.

Fixes [YOCTO #10586 ].
