Allow wine ws2_32:sock regression test to complete

Attention: ws2_32:sock test does cause failures even on 2k3sp2 WHS bot, which means the test itself is not correct: https://reactos.org/testman/compare.php?ids=89609

additionally to that it causes real crashes when run under ros:
For some time the ws2_32:sock winetest has not provided testbot results due to two different hangs. See (https://reactos.org/testman/compare.php?ids=60023,60025). These two tests are part of the sock.c test and are as follows:

1) test_write_watch
2) test_ConnectEx

For the first one, it depends upon some as yet unimplemented MEM_WRITE_WATCH functionality in ReactOS, so I added a '#ifdef REACTOS' to the test to skip it.

For the other one according to dll/win32/msafd/misc/stubs.c there are three associated unimplemented functions as follows:

1) WSPAcceptEx
2) WSPConnectEx
3) WSPDisconnectEx

So I have #ifndef'ed all three of these tests for now. This test is currently black-listed.
In my testing, I have seen much variability in the number of tests done run-to-run.
It is not obvious why we have this, but it is there for anyone to see.

I plan to do another testbot run and then follow it by a PR soon.
