libtirpc is a shared library, it'll still be loaded as long as anyone
needs it, and I'm not convinced we'll be able to get rid of all users.

I'm not sure it's bringing us a real practical advantage at this point,
compared to rpc.mountd, which can act either as a daemon that only
processes v4 upcalls or can do both, depending on how you start it.
