Some minor touch-ups to the SVG content-model test framework

LayoutTests/svg/dom/resources/svgtags.js

 // A list of all SVG tags plus optional properties:
 //   * needParent       (string)        - parent element required for a valid context
-//   * needChld         (string list)   - child element(s) required for a valid context
+//   * needChild        (string list)   - child element(s) required for a valid context
 //   * needAttr         (string map)    - attribute(s) required for a valid context
 //   * noRenderer       (bool)          - true if the element doesn't have an associated renderer
