Do not truncate long options in arg_show_usage()

Instead of writing options to a fixed-sized buffer with snprintf(),
which truncates options longer than the buffer size, simply call
fprintf() and use its return value to detect if the option is too long
and its description should start on the next line.

Before:
            --use-intra-default-tx-onl  Use Default-transform only for INTRA modes
After:
            --use-intra-default-tx-only=<arg>
                                        Use Default-transform only for INTRA modes
