lavu/opt: use AV_DICT_MULTIKEY in av_opt_set_dict2()
If the dictionary provided on input contains multiple entries for an
option (relevant for flags modifying the previous value with '+' or
'-') and the option is not found in the target object, only the last
entry would be returned to the caller.
Pass AV_DICT_MULTIKEY to av_dict_set() to make sure all such entries are
returned.
