Richard W.M. Jones b48e885004 sysprep: Add disks with discard = "besteffort".
Since virt-sysprep tends to delete a lot of files, adding discard
support to it makes some sense.

Note that this probably won't have any effect for most filesystems
since:

(a) ext4 mounts also need to use -o discard,

(b) ext4, and maybe others, require you to call fstrim explicitly,
they don't discard automatically (except for userspace tools like
mkfs.ext4 but that doesn't apply in this case).
