oe/license_finder: don't return the "crunched" license text in crunch_license

crunch_license() will perform some basic text manipulation to try and
canonicalise the license texts. It also returns the new license text but
none of the callers use this, and as a slightly mangled version of the
original it has no real purpose.

Remove this return value and clean up the callers.
