kernel - sysctl - use a larger buffer to ensure that a ksnprintf() fits

* Use a larger buffer to ensure that a ksnprintf() fits.  This doesn't
  fix any bugs per-say but it does ensure that any normal integer OID
  will be properly displayed.

* No current sysctls have OIDs large enough to have triggered the problem.
