libcamera: yaml_parser: Return nullopt on error
The YamlParser::getList<>() function returns an std::optional<> to allow
callers to identify cases where parsing the .yaml file failed from cases
where the parsed list is just empty.
The current implementation returns a default constructed std::optional
in case of errors with
return {};
The returned value is thus equal to std::nullopt, but the code can be
easily misinterpreted as returning an empty vector by a reader.
