Ninja: do not normalise swift support file paths

When building the output-map-file.json, do not convert the path to a
Ninja path, which will make it relative.  If `cmake` is invoked with the
`-B` option the files will be written relative to the directory where
CMake was invoked rather than relative to the build tree.  This path
need not be a relative path since it is used internally by CMake to
determine where to write the output map file.  This allows the use of
`-B` option in CMake in projects with Swift targets.
