bitbake.conf: propagate 'opengl' DISTRO_FEATURE to native/nativesdk from target
This will allow better control over native virgl/qemu configurations.
Adjust gtk+3/cairo native configurations to actually ignore opengl
when building for -native: we do not need it, and it would cause build
failures as only a limited subset of mesa-native is currently built.
Drop native/nativesdk overrides from virglrenderer/libepoxy recipes
as opengl feature is now correctly set for those variants.
