Move expected location of jsexec.ini from exec directory to ctrl directory:

- argv[0] does not always contain the full path to the executable, so that is
  not a good way to locate the exec directory.
- since we already need to know the ctrl dir and that is the normal place to
  put config files, that's where it shall be.
- jsdoor builds don't get a .ini file - I don't think they need it (?)
