virtiofsd: remove mountpoint dummy argument

Classic FUSE file system daemons take a mountpoint argument but
virtiofsd exposes a vhost-user UNIX domain socket instead.  The
mountpoint argument is not used by virtiofsd but the user is still
required to pass a dummy argument on the command-line.

Remove the mountpoint argument to clean up the command-line.
