File opae-support-OBS-build.patch of Package opae

commit 10e14b8f771bc38ca07b3228f791793b0e277d09
Author: Nicolas Morey-Chaisemartin <nmoreychaisemartin@suse.com>
Date:   Wed Oct 7 10:52:08 2020 +0200

    opae: support OBS build
    
    By default opae downloads external packages.
    Add a flag that disabled this and relies on OBS/rpmbuild to have installed the system requirements
