apparmor: allow yggdrasil to resolve hostnames (#739) 
The apparmor profile in it's current state won't allow resolving hostnames. We need `<abstractions/nameservice>` because we simply can't just allow `/etc/resolv.conf`. This is because systemd-resolved, resolvconf, and others rely on symbolic links to `/etc/resolv.conf` which would make this extremely complicated.  `<abstractions/nameservice>` deals with this complexity to allow every single one of those packages (systemd-resolved, resolvconf, ... ).

```
  network inet stream,
  network inet dgram,
  network inet6 dgram,
  network inet6 stream,
  network netlink raw,
```
was removed because it's already included in `<abstractions/nameservice>`. Some permissions that are no longer needed in newer yggdrasil versions were also removed.

`owner /sys/kernel/mm/transparent_hugepage/hpage_pmd_size r,` was changed to `/sys/kernel/mm/transparent_hugepage/hpage_pmd_size r,` because there is no guarantee that yggdrasil will always be run as root. (`owner` makes sure that the process's user and the file have the same owner, in that case, root. This might not always be the case so `owner` was removed)

Change DefaultIfName from "/dev/tun0" to "tun0" 
Specifying the full path to the interface in OpenBSD would result in:
panic: Interface name must be tun[0-9]*

Therefore, DefaultIfName should be changed to tun0 in order to make yggdrasil work out of the box.
