witness: actually set read-only tunables in time for witness_startup

SYSCTL_XXX with CTLFLAG_RDTUN and without CTLFLAG_NOFETCH should not be
used for values that are needed before SI_SUB_KLD.  Otherwise they are
tuned after they are needed.  Set CTLFLAG_RDTUN | CTLFLAG_NOFETCH for
the debug.witness.witness_count and debug.witness.skipspin sysctls and
add separate tunables for them, which run at SI_SUB_TUNABLES time, i.e.,
in time for witness_startup.
