fix build with g++ : error: ‘sei_scalability_priority_layer_info_t’ does not name a type

[mpromonet]

Trying to compile a simple main like :

#include "h264_stream.h"
int main() {
    return 0;
}

Fails with the error :

In file included from h264_stream.h:31:0, from test.cpp:1: h264_sei.h:113:10: error: ‘sei_scalability_priority_layer_info_t’ does not name a type; did you mean ‘sei_scalability_layer_info_t’? typedef sei_scalability_priority_layer_info_t; ^~~~~~~~~ sei_scalability_layer_info_t

This pull request remove the typedef that seems an old forward declaration.

Best Regards Michel.

Yes, this seems like leftover old code.
