fallbacksrc: Don't configure conversion elements for normal stream
Internal conversion element can cause unexpected format/resolution
change depending negotiated result, which didn't happen before
the recent fallbacksrc update for fallback stream support.
Configure conversion objects only for fallback streams and also
fallback-{audio,video}-caps are specified, in order to keep
previous behavior.
