Daniel P. Berrangé 48e32b429d Fix copyright header to specify GPLv2 or later, not GPLv2 only.
The copyright headers in every file were chjanged in this previous commit

  commit b6dcee8eb7
  Author: Cole Robinson <crobinso@redhat.com>
  Date:   Tue Mar 20 15:00:02 2018 -0400

    Use consistent and minimal license header for every file

Where before this they said "

  "either version 2 of the License, or (at your option) any later version."

Now they just say

  "GNU GPLv2"

This fixes it to say "GNU GPLv2 or later" again.
