    bsdinstall: stop messing with file descriptors

    Throughout the bsdinstall script fd 3 is used by f_dprintf (set through
    $TERMINAL_STDOUT_PASSTHRU). By closing file descriptor 3 here, the
    final f_dprintf "Installation Completed ... does not work anymore.

    By putting the code into a subshell, file descriptors can be edited
    without interference with the calling script.
