Ensure that the fragment to close the header (`</div>\"]`) is written when the
function `mermaid_print_section_header` is called only once, which happens when
the filtergraph has no inputs.
Integer writing is impossible here as the first branch was dead code,
so remove it completely.

The key benefits are:
- Different to other graph printing methods, this is outputting:
- all graphs with runtime state
(including auto-inserted filters)
- each graph with its inputs and outputs
- all filters with their in- and output pads
- all connections between all input- and output pads
- for each connection:
- the runtime-negotiated format and media type
- the hw context
- if video hw context, both: hw pixfmt + sw pixfmt
- Output can either be printed to stdout or written to specified file
- Output is machine-readable
- Use the same output implementation as ffprobe, supporting multiple
formats
