sys_clock: start the microkernel ticker in the MICROKERNEL init level

The ticker was always initialized in the NANOKERNEL init level. In a
microkernel, this can cause problems if for the some reason the
initialization of the microkernel server is delayed, such as devices
initialization in the NANOKERNEL level taking non-insignificant time to
complete. What happens in that case is the ticker ISR will start firing
and piling up events in the microkernel server stack, and quite quickly
overrun it, since it has a finite size, causing random crashes.

So, in the microkernel, initialize the ticker once the microkernel
server is available. There is no point in sending ticker event before
anyway.
