[collectd] strange df output

These /tmp/tmp-XXXXXXXXX filesystems are caused by xen-tools' 
xen-create-image utility. During domU creation, the domU's root filesystem 
is mounted at these mountpoints for OS creation.

They're only mounted briefly, but collectd does pick them up & create RRD 
if not ignored.
