    jail.8: Update the man page for allow.nfsd
    
    Commit bba7a2e89602 added "allow.nfsd" to optionally allow
    mountd/nfsd to be run inside a vnet prison when the kernel
    is built with "options VNET_NFSD".
    
    This patch updates the man page for this change.
    
    This is a content change.
    
    (cherry picked from commit d4b4f3b9c356938de6140ccea20d502d207b18a7)
