[Pkg-libvirt-maintainers] Bug#684885: update-guestfs-appliance fails for wheezy because it looks for 'diff' instead of 'diffutils'

[Guido Günther]

The error message is:

Fetched 79,4 MB in 1min 16s (1.037 kB/s)                                                                                                                                                          
febootstrap: aptitude: error: no file was downloaded corresponding to package diff

after downloading the packages. Changing diff to diffutils in
/usr/lib/guestfs/packagelist makes update-guestfs-appliance finish as
expeced.
