apparmor: allow libvirtd to send signals to unconfined processes

When confinement of QEMU/KVM domains is not enforced (security_default_confined = 0),
qemu processes run unconfined. Add a rule to the libvirtd apparmor profile allowing
sending signals to unconfined processes. Without the rule, libvirtd
is unable to signal QEMU/KVM domains. E.g. 'virsh destroy dom' results in the
following denial in audit.log

type=AVC msg=audit(1510951646.581:939): apparmor="DENIED" operation="signal"
profile="/usr/sbin/libvirtd" pid=18891 comm="libvirtd" requested_mask="send"
denied_mask="send" signal=term peer="unconfined"
