lavc/dnxuc_parser: Use av_fourcc2str instead of av_fourcc_make_string

Browse Source 
The documentation of av_fourcc_make_string states the passed in
buffer must be of at least the size of AV_FOURCC_MAX_STRING_SIZE .

Using av_fourcc2str uses the correct buffer size and moves the
buffer into a nested scope while also being shorter.
