apparmor: Use abstractions/nameservice to deal with symlinked resolv.conf

Browse Source 
While abstractions/nameservice appeared too broad and overkill for
our simple need (read-only resolv.conf access), it properly deals
with symlinked resolv.conf files generated by systemd-resolved,
NetworkManager or suchlike.

If we just grant read-only access to /etc/resolv.conf, we'll fail to
read nameserver information in rather common configurations, because
AppArmor won't follow the symlink.
