  ipfw: Add sysctl flag CTLFLAG_TUN to loader tunables

The following sysctl variables are actually loader tunables. Add sysctl
flag CTLFLAG_TUN to them so that `sysctl -T` will report them correctly.

 1. net.inet.ip.fw.enable
 2. net.inet6.ip6.fw.enable
 3. net.link.ether.ipfw

No functional change intended.

  ip_mroute: Fix sysctl knobs

The loader tunable `net.inet.ip.mfchashsize` does not have corresponding
sysctl MIB entry. Just add it.

While here, the sysctl variable `net.inet.pim.squelch_wholepkt` is actually
a loader tunable. Add sysctl flag CTLFLAG_TUN to it so that `sysctl -T`
will report it correctly.
