Hmm, doh.  I document the other loader tunables and sysctls, just not
debug.witness_watch.  If someone with some mdoc fu and spare time wants to add
a para noting that debug.witness_watch can be set to 0 as a loader tunable to
turn off witness and that the read-only sysctl debug.witness_watch can be used
at runtime to see if witness is enabled or not.
