[PATCH v4 3/4] user32/tests: Workaround an intermittent failure. (resend)

[Zebediah Figura]

Fixes https://bugs.winehq.org/show_bug.cgi?id=42568

Since the message timing is incorrect, the child's SendMessage() may
sometimes precede the main thread's PeekMessage(), causing additional
tests to fail. Adding a short thread sleep should prevent this.
