codecparsers: h264: fix identification of EOSEQ and EOS NALs.

Browse source 
An end_of_seq() [EOSEQ] or end_of_stream() [EOS] NAL unit is really
one byte long because this shall include the NalHeaderBytes (1) too.
The NALU.offset starts from the first byte of the header.

This is the proper fix to commit d37f842. In practice, this fixes
parsing of FRExt1_Panasonic_D and FRExt2_Panasonic_C, that include
additional frames after an EOSEQ.
