apache: Cleanup domain configuration

- Don't set log level explicitly. Fallback to value set in global Apache
  configuration.

- Don't set directory options already set in global configuration.

- Remove /cgi-bin/. Only ikiwiki uses cgi and it is served from a different path
  than /usr/lib/cgi-bin.
