nanokernel: allow nano time tracking to be used in microkernels
The nanokernel time tracking code (ticker) can now exist in microkernel
systems. This allows the ticker that drives nano timers and timeouts to
advance the tick count for these in a microkernel, thus allow their
presence there. Previously, nano timers could not be used in a
microkernel.
