[OE-core] [PATCH] base.bbclass: support for or operand in LICENSE and for SPDX license names

[Andrei Gherzan]

From: Andrei Gherzan <andrei.gherzan at windriver.com>

base.bblass modfied in order to correctly exlude packages where OE-Style licence naming
is used. In this way licenses as GPL-3, GPLv3, GPLv3.0 will be exluded from a non-GPLv3
build.
The second modification was to include in a non-GPLv3 build packages where LICENSE is
GPLv3 or "something else". For example, qt4-embedded has LICENSE = "LGPLv2.1 | GPLv3".
This package should be included in a non-GPLv3 build as it is LGPLv2.1 or GPLv3.
