[PATCH 1/2] create-spdx.bbclass: Simplify extraction of license text

[Peter Kjellerstedt <pkj@axis.com>]

There is no reason to first search for all available licenses using
avail_licenses() and then search through the same paths looking for
the actual license texts. Just look for the license texts directly
instead.
