Mark Johnston fdeb273d49 dtrace: Add some more annotations for KMSAN 
- Don't allow FBT and kinst to instrument the KMSAN runtime.
- When fetching data from the traced thread's stack, mark it as
  initialized.  It may well be uninitialized, but as dtrace permits
  arbitrary inspection of kernel memory, it isn't very useful to raise
  KMSAN reports.
- Mark data copied in from userspace as initialized, as we do for
  copyin() etc. using interceptors.
