Fix for systemd-based Debian systems
Fix guestfs, supermin appliance path

The supermin appliance files are not installed to the multiarch lib directory.
debian: Revert 3ed3e23ed (no febootstrap copy-kernel option).
ubuntu: Work around buggy lvcreate/udev in Ubuntu 12.10 and 13.04.

lvcreate and udev somehow don't interact well, so when lvcreate is
creating the LV, udev doesn't create the device node in time, causing
the following error:

 /dev/VG/LV: not found: device not cleared

The workaround here is to tell lvcreate not to zero the newly created
LV.  This means that lvcreate won't try to open the device, so doesn't
notice that it is missing, and hence doesn't fail.
ubuntu: Remove blank-disk.img test.

Ubuntu 12.10 has ancient parted (2.3) which gives an error on a
completely blank disk, breaking the 'part-list' command (amongst
others):

  guestfish -a tests/guests/blank-disk.img run : part-list /dev/sda
  Error: /dev/sda: unrecognised disk label

Remove this disk to avoid failures in virt-alignment-scan and other
tests.
ubuntu: sysprep: Disable lvm-uuids when testing.

It fails like this:

sysprep operation failed: exception: Guestfs.Error("pvchange_uuid_all:   Volume group containing /dev/sda2 has active logical volumes")

Possibly related to broken udev rules in Ubuntu.
