supervisor-xqueue: Fix duplicate declaration of default variable `XQUEUE_BASIC_AUTH`
supervisor-xqueue: Fix duplicate declaration of default variable `XQUEUE_BASIC_AUTH`

`XQUEUE_BASIC_AUTH` was declared twice for two different usages: activating/deactivating
the auth (boolean), and a [login, password] list. Split the second usage (login/password
list) into two separate variables, like the corresponding django_auth variables.
