Re: [Libguestfs] [v2v PATCH] nbdkit, qemuNBD: run_unix: formally require externally provided socket

At this point, virt-v2v never relies on the Unix domain sockets created inside the "run_unix" implementations. Simplify the code by removing this option. Consequently, the internally created temporary directory only holds the NBD server's PID file, and never its UNIX domain socket. Therefore: (1) we no longer need the libguestfs socket dir to be our temp dir, (2) we need not change the file mode bits on the temp dir, (3) we can rename "tmpdir" to the more specific "piddir".
