Brad King 8ee6584a99 Ninja,Makefile: Fix <LANG>_COMPILER_LAUNCHER shell command syntax 
The first entry in the compiler launcher command argument list is
the command itself and should be converted to the shell's native
command syntax (e.g. backslashes on Windows).

Without this, the `RunCMake.CompilerLauncher` test fails on Windows
when there are *no* spaces in the path to `cmake.exe`.
