[PATCH v2 3/3] ntdll/tests: Add a test for closing a completion port being waited on.

[Alexey Prokhin]

The test reproduces a hang by Planet Zoo when exiting the game.

v2: Update kernelbase patch. Supersedes 184509

Given it is one of my first contributions to wine, I have a few
questions/notes:

1.
> LPTHREAD_START_ROUTINE test_routines[] = {

I didn't find such pattern anywhere else in the tests, but I hope
it's ok.

2.
> ok( info[0].CompletionKey == 0xdeadbeef || info[0].CompletionKey == 0,

I am not sure if info should be checked at all in the case. And if
it is, should I mark the second equality as broken? (Because info
is only zeroed out on win server 2008)

3. Is it ok there is a test for GetQueuedCompletionStatus. Or
should it be moved to kernelbase?

4. Should a test for GetQueuedCompletionStatusEx also be added?
