kernel: initialize system work queue after kernel is up

The system work queue spawns a coop thread to hanlde the work items. If
it is spawned before the kernel is up and the initialization dummy
thread's priority is lower, there will be a context switch into the
system work queue's thread at that time, before the kernel is ready to
handle this.
