Rick Macklem 0bb08f21cc rc.d: Fix NFS server startup scripts to enable vnet prison use
Now that commit cbbb22031f is in main,
it is possible to run nfsd(8), nfsuserd(8), mountd(8),
gssd(8) and rpc.tlsservd(8) in an appropriately configured vnet
prison if the "allow.nfsd" option is specified in jail.conf.

This patch fixes the rc scripts for this.
Mostly just replaces the "nojail" KEYWORD with "nojailvnet",
but also avoids setting vfs.nfsd.srvmaxio in a prison, since it
must be set outside of the prisons and applies to all
nfsd(8) instances.
