test-logtoprocess: use cat to wait for outputs
Commands started by logtoprocess are running asynchronously. To be able to
test the output, we need to block and wait for the output.
The patch uses "| cat" to wait for such "asynchronous" outputs, to make the
test more reliable. I have also written a short notice at the top, hopefully
people would be aware of the pitfall when changing the test.
