The list_guests function in libvirt-guests uses 'grep -v' to filter
Xen domain0 from a list of guests. If domain0 is the only item in
the list, 'grep -v' returns 1, causing the 'stop' operation to fail
when action is 'suspend'. Improve the filtering by using sed to remove
domain0 from the list of guests.

Failure of the 'stop' operation was fixed in commit 69ed99c7 by marking
domain0 as a persistent domain. That fixes cases where domain0 is the
only domain in the list of persistent domains. But there may be cases
where domain0 is the only domain in 'virsh list --uuid', and the code
should be made more robust to handle those.
