nfsd: decode implementation id
Decode the implementation ID and display in nfsd/clients/#/info. It may
be help identify the client. It won't be used otherwise.
(When this went into the protocol, I thought the implementation ID would
be a slippery slope towards implementation-specific workarounds as with
the http user-agent. But I guess I was wrong, the risk seems pretty low
now.)
