Chris Tate faa5cb601a Route defineProperty replacements of child methods through the child's box, and size the getter-only error to the name

- The scan for properties JavaScript adds to children now also records `Reflect.defineProperty`, `Object.defineProperty` and `Object.defineProperties` on a child, and element writes (`child["kill"] = ...`). A key that is not a literal sends every member through the child's box. A typed call to a method replaced through `Reflect.defineProperty` then calls the replacement instead of the native method.
- The "Cannot set property x of #<ChildProcess> which has only a getter" message is built at its exact length. Before, a name that overflowed the 160-byte buffer passed the untruncated length to the throw, which read past the buffer.
- Corpus 6611 adds a module that replaces kill through Reflect.defineProperty and writes to a getter-only property with a 300-character name; 6610 and 6611 get their cost files.
