Explicitly use "python" ijson backend (pantsbuild#17787)

ijson provides a few backends with varying levels of compatibility and performance; which backend is chosen by ijson is system-dependent. Unfortunately the yajl2 backend does not play nicely with the JSON output by go list and throws an IncompleteJSONError when parsing.

As a workaround, we can explicitly use the pure Python backend which is able to parse Go's output correctly.

Closes pantsbuild#17778
