perf kwork: Make perf_kwork_add_work a callback

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.
