Subject: [PATCH] [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.
