When I moved the client name to be last, I did not account for the fact
current code skips showing engine utilisation until at least two sampling
periods have passed. Consequence of this is that client name gets printed
as the second field and not under the "NAME" column header.

Fix it by emitting spaces instead of engine utilisation until two samples
have been collected.
