manpage: explain why showmount doesn't really work against a v4-only server
From: Jeff Layton <jlayton@redhat.com>
I occasionally see people that expect valid info when running showmount
against a server that may export some or all filesystems via NFSv4.
Let's make it clear that it only works by talking to the remote MNT
service, and that that may not be available from a v4-only server.
