kernel - Add some sysctls to kmalloc_obj

* kern.kzone_pollfreq (default 1hz) - Set polling frequency for
  kmalloc zone cleanups.

* kern.kzone_bretire (default 4) - Set number of zones the kmalloc
  poller can retire per interval.  Too high a number can create
  noticable system stalls due to kernel_map operations.

* Add a few more fields to the kmalloc_mgt structure.  Track
  retirement count to help with debugging.
