Broken WoW builds

[Francois Gouget]

So as far as I can tell the following patch broke the WoW builds:

commit a1cdcc5290618c00d73e7a71aaa38897ec501138
Author: Alexandre Julliard 
Date:   Mon Jun 17 09:28:35 2019 +0200

ntoskrnl: Build with msvcrt.

Signed-off-by: Alexandre Julliard

That is, after this patch, I get a crash in mountmgr.sys when creating 
the wineprefix (see attached backtrace). Maybe I'm missing something.

Anyway, this is why the TestBot has been failing all patches for a 
while: all patches are tested against wow32 and wow64 builds but those 
were unable to run the tests.

So for now I have disabled testing on the wow builds.
