svn commit: r365955 - head/sys/sys

Log:
  Hide tunable definitions behind _KERNEL
  
  Some userspace code include sys/kernel.h. Namely, some OpenZFS tests do
  this, and it was causing breakage after r365945 due to a lack of bool
  typedef. Userspace should not need the TUNABLE_** stuff, so hide it
  behind an #ifdef _KERNEL.
  
  Sorry for the breakage.
