On machines where os.tmpdir() returns a path with a space (e.g.
/Volumes/Mini Me/tmp), runGsdTools() string args were whitespace-split by
the helper tokeniser, truncating paths at the first space. Switch all
calls that embed a dynamic path into the argument list to the array form
of runGsdTools() so execFileSync receives each path as a single argv slot.
Fixes#3509
