[Scott Moser]

create disk.local the same way ephemerals are created (LP: #851145)

If the user did not specify '--block-device-mapping /dev/vdb=ephemeral0', then
then the first non-root device would end up being created differently then
if they had. It would not have a filesystem on it.

This makes 'local_gb' in the libvirt connection created the same way that
it would be if it were named ephemeral0.
