fix(kyber): correct IFEO backslash count and add shim validity check

Browse Source 
system.reg values use \\ for one backslash, so C:\shim\kyber_cmd.exe
must be written as C:\\shim\\kyber_cmd.exe. The previous script wrote
C:\\\\shim\\\\kyber_cmd.exe (4 backslashes = two literal backslashes),
which Wine couldn't resolve.

Also detect when the shim slot contains Wine's cmd.exe (122231 bytes)
left behind by a failed earlier attempt, and recompile automatically.
