tests: Get rid of asynchronous process substitution

Under bash, processes substitution is run asynchronously. This means
that the messages printed by the process can be mixed with other
messages, which causes random tests to fail, because the wvtest
protocol lines are corrupted.

Now we run all processes synchronously and the test no longer fail
randomly.
