Make stats analysis working with empty layers (bitrate=0)

Browse Source 
Setting layer's target bitrate to zero is a valid scanario. Example of command line: out/debug/video_codec_perf_tests --gtest_also_run_disabled_tests --gtest_filter=*EncodeDecode --encoder=libvpx-vp9 --decoder=libvpx-vp9 --scalability_mode=L2T1_KEY --width=640 --height=360 --bitrate_kbps=0,400
