docs: Document I idle state in ps and top

Linux 4.2 provided a new process state of I which is used for an idle
kernel thread. This new state means that kernel threads do not
contribute to the loadavg as they are no longer state D or S but I.

While both ps and top displayed this state, it wasn't documented in
either manual page until now.
