apparmor: Allow lxc processes to receive signals from libvirt
    
    LXC processes confined by apparmor are not permitted to receive signals
    from libvirtd. Attempting to destroy such a process fails
    
    virsh --connect lxc:/// destroy distro_apparmor
     error: Failed to destroy domain distro_apparmor
     error: Failed to kill process 29491: Permission denied
    
    And from /var/log/audit/audit.log
    
    type=AVC msg=audit(1606949706.142:6345): apparmor="DENIED"
    operation="signal" profile="libvirt-314b7109-fdce-48dc-ad28-7c47958a27c1"
    pid=29390 comm="libvirtd" requested_mask="receive" denied_mask="receive"
    signal=term peer="libvirtd"
    
    Similar to the libvirt-qemu abstraction, add a rule to the libvirt-lxc
    abstraction allowing reception of signals from libvirtd.
