show an error message if an old calling convention is detected,

i.e. if there are command-line 2 arguments and the 1st one is a *.xdy file.

in this case older version of xindy script was calling xindy.v2,
which has been deprecated and not installed anymore.

therefore, we cannot call xindy.v2, but should show an error message,
otherwise this may confuse users who were relying on this behavior of
silent call to xindy.v2 from xindy
