mbuf: 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. kern.ipc.mb_use_ext_pgs
2. kern.ipc.nmbclusters
3. kern.ipc.nmbjumbop
4. kern.ipc.nmbjumbo9
5. kern.ipc.nmbjumbo16
6. kern.ipc.nmbufs
No functional change intended.
