CMakeDetermineCompilerId: Look for internal file only on host 

The find_file this module uses to locate the compiler id source file
must always look on the host and never in CMAKE_FIND_ROOT_PATH, even
when a toolchain file has

 set(CMAKE_FIND_ROOT_PATH_MODE_INCLUDE ONLY)

Add NO_CMAKE_FIND_ROOT_PATH to the find_file call to avoid rerooting.
