In 012d87c1fc/cc8f398202 it was made possible for fork_notify() to return in the child but at that point all FDs were closed and the _cleanup path from the return causes assertion failures due to invalid FDs in notify_event_source/event, leading to a vmspawn failing to start with a SIGABRT logged in coredump. Instead of TAKE_PTR on a bunch of things which is fragile, rather avoid the return and instead add an explicit callback handler and guarantee to exit directly after it. A userdata argument is also added but not used yet I think it's quite normal to have for a callback.
