[gparted] Disable unmount of busy jbds (#89)

[Curtis Gedak <gedakc src gnome org>]

commit 20d7835fcc5e327f818c830b323cea5472b38ce9

    Disable unmount of busy jbds (#89)
    
    GParted automatically enables the Partition > Unmount action for busy
    partitions.  This is not going to be supported for jbds so disable it.
    
    Closes #89 - GParted doesn't recognise EXT4 fs journal partition
