Add Xfce desktop shortcut to draklive-install at run time, not build time.

Xfce has added an extra restriction on executable desktop files in the
Desktop directory. They now need to have a xfce-exe-checksum extended
file attribute as well as having execute permissions. We can't add
this at build time because squashfs does not support system extended
attributes.
