MINOR: Fix race condition in TestVerifiableProducer sanity test
The test starts a producer, waits for at least 5 acks, and then
logs in to the worker to grep for the producer process to figure
out what version it is running.
The problem was that the producer was set up to produce 1000 messages
at a rate of 1000 msgs/s and then exit. This means it will have a
typical runtime slightly above 1 second.
Logging in to the vagrant instance might take longer than that thus
resulting in the process grep to fail, failing the test.
This commit doesn't really fix the issue - a proper fix would be to tell
the producer to stick around until explicitly killed - but it increases
the chances of the test passing, at the expense of a slightly longer
runtime.
