[PATCH blktests] nbd/rc: redirect nbd-server stderr
Recent nbd commit da5e07c057ab ("Reimplement daemonize() without using
daemon()") changed how nbd-server daemonizes itself. After this commit,
nbd-server prints messages to stderr after daemonization. This caused
nbd test cases to fail due to unexpected stderr output.
