Ben Boeckel 35d32b8741 cmLocalGenerator: move the CMakeFiles subdir from the target to output root 
When target directories are shortened, the `CMakeFiles` path component
will be part of the root, not the target directory. Since other files
end up constructing paths manually, move the differing component into
the correct logical path construction part.
