insane,license,license_image: Allow treating license problems as errors
Use the same WARN_WA and ERROR_QA variables as insane.bbclass to allow
individual recipes, the distro or other configuration to determine
whether the various detected license errors should be treated as a
warning (as now) or as an error.
oe.qa.handle_error isn't immediately fatal, so oe.qa.exit_if_errors must
be called at the end of do_populate_lic to fail the task.
