perf_kwork_add_work is declared in builtin-kwork, whereas much kwork code is in util. To avoid needing to stub perf_kwork_add_work in python.c, add a callback to struct perf_kwork and initialize it in builtin-kwork to perf_kwork_add_work - this is the only struct perf_kwork. This removes the need for the stub in python.c.
