[CMAKE]
Attempt to fix a concurrency issue with midl. Regarding to the MSVC builder output, midl
failed when compiling wine/itss.h due to a concurrent access to itss_i.c. Although the
command to generate itss.h doesn't seem to geenrate itss_i.c (at least not on my wdk
buld), I added a switch to rename that file.
