modules: Start using @SOURCE_ROOT@ and @BUILD_ROOT@

First step in fixing https://github.com/mesonbuild/meson/issues/1419

Also works around an issue in the MinGW windres.exe that causes it to
fail if any of the arguments passed to it contain a space. There seems
to be no way to quote or escape the spaces in the path to make windres
parse the path correctly, so we just warn about it instead.
