package/python-daphne: new package

Daphne is a HTTP, HTTP2 and WebSocket protocol server for ASGI and ASGI-HTTP,
developed to power Django Channels.

It supports automatic negotiation of protocols; there's no need for URL
prefixing to determine WebSocket endpoints versus HTTP endpoints.

In addition, add the patch: remove pytest-runner-requirement.
Setup and runtime work without without pytest-runner as such, it is not actually
a requirement for building.
