Remove references to QPL in LICENSE

QPL is an available choice for the license within the QtE 2.3.10 source,
but would never be a practical selection for us because it is not
GPL-compatible, so there's no point in mentioning it. Removing it fixes
a warning as well (since we have no generic QPL license file).
