avcodec/h264: support sps/pps AV_PKT_DATA_NEW_EXTRADATA

Browse Source 
Commit 601c238854 added support for AV_PKT_DATA_NEW_EXTRADATA, but
only for avcC extradata.
This commit adds support for sps/pps extradata as well. This makes
support consistent for passing new extradata consistent with the
types of extradata that can be passed when initializing the decoder.
