AppArmor: Explicitly allow netlink raw socket for Supervisor (#370)

The Supervisor uses netlink raw sockets to get access to udev events
sent through netlink. Technically, the rules so far have denied all raw
sockets. However, in practice it seems that netlink raw sockets have
still been working.

For unknown reasons, in Debian Bookworm that behavior changed: The rule
now also denies netlink raw sockets.

This new ruleset starts off with the default setting (where almost
everything seems to be denied), and enables explicitly what is needed
in Supervisor. In tests this ruleset worked on Home Assistant OS as well
as Debian Bookworm.

Fixes: home-assistant/supervisor#4381
