Enji Cooper d6701b6c8c Add kern.features.witness 
Adding `kern.features.witness` helps expose whether or not the kernel has
`options WITNESS` enabled, so the `feature_present(3)` API can be used
to query whether or not witness(9) is built into the kernel.

This support is helpful with userspace applications (generally speaking,
tests), as it can be queried to determine whether or not tests related
to WITNESS should be run.
