[Fabrice Fontaine]

Commit 5a393677314dfdaa6a4bd6a847b642ae54517538 forgot to update
license which has been changed from COPYING to LICENSE.GPL2 and
LICENSE.LGPL2.1 since version 4.0.0 and
https://github.com/lxc/lxc/commit/cc73685dd09315b292968ee91a08a8f295376b35

It should be noted that COPYING describes GPLv3, see upstream answer
here: https://github.com/lxc/lxc/issues/3484

Fixes:

Changes v1 -> v2 (after review of Thomas Petazzoni):
 - Specify that GPL-2.0 is for some tools (6 source files)
 - Add link on upstream answer for COPYING
