x264enc: fix up avcC header construction and playback by flash players

Browse source 
Fix off-by-one bug when constructing the avcC header chunk: we
wrote wrong profile info into the header. The first byte in the
SPS NAL we get from x264 is the nal type, not the profile_idc.

Also add some debug logging.

Fixes #610089.
