package: allow 'tee' to catch up before returning (re: beb3c64a)

Browse source 
In the referenced commit message I neglected to mention that, when
doing bin/package make, we're now running 'tee' in the background
again and the building job in the foreground, as opposed to the
other way around. Foreground jobs are more reliably interruptable.
But that reintroduced the problem fixed in 5b8d29d3. Now I don't
know what I was thinking then -- the obvious fix is to add a 'wait'
command, allowing 'tee' to catch up before returning to the prompt.
