Accepting request 843706 from home:darix:playground

- update apparmor profiles to get warning free again on 15.2
  - use abstractions for ssl files
  - allow inet dgram sockets as mumble can also work via udp
  - allow netlink socket (probably for dbus)
  - properly allow lsb_release again
  - add support for optional local include
- start murmurd directly as user mumble-server it gets rid of the
  dac_override/setgid/setuid/chown permissions
