[PATCH 1/6] user32/tests: Wait more for ShowWindow(SW_SHOWMINIMIZED):overlapped test.

The first messages in the sequence are generated right away by the
SW_MINIMIZE request, but the last ones are only a result of the native
driver implementation of the window minimization and may take some time
to be received, or may not be received at all.
The test spuriously succeeds in the case where the driver messages are
not received and only the optional messages at the end of the sequence

The test actually passes on all the testbot runs I could start. It
fails locally though -testing with fvwm in Xephyr- from time to time
because the WM sometimes reacts fast enough.
I'm not sure if that's a specificity of the testbot WM configuration,
it looks like minimizing windows there does not trigger anymore
messages not matter how long we wait.
