avformat/utils: Use av_realloc_array for reallocating array

Also improve the size check a bit; given that av_realloc_array()
checks for overflow itself, we only have to check for
nb_side_data + 1 still being representable in an int.
But given that we can check for representability in size_t
at no additional cost we do so as it leads to a nicer error code.
