[PATCH] ptrace: make pid of child process available for PTRACE_EVENT_VFORK_DONE
When delivering PTRACE_EVENT_VFORK_DONE, provide pid of the child process
when tracer calls ptrace(PTRACE_GETEVENTMSG). This is already
(accidentally) available when the tracer is tracing VFORK in addition to
VFORK_DONE.
