[file-roller] Detach the child process from the tty.

[Paolo Bacchilega <paobac src gnome org>]

commit 6429de3d50e759afd71c3557e39c83194e041cac
Author: Paolo Bacchilega <paobac src gnome org>
Date:   Wed Jul 15 10:24:09 2009 +0200

    Detach the child process from the tty.
    
    This avoids the child process from asking the password when
    file-roller is started from a terminal.
    
    [fixed bug #588547]
