Eric Schnoebelen in PR 28821, with some modifications by myself (for

Tested by myself on NetBSD/i386, and on NetBSD/amd64 by Quentin Garnier.
because their #! lines contained an incorrect path. Also, even if
they had actually pointed to the installed "festival", it would still
not have worked because a script cannot be used as a script
interpreter. Even if it could, it still wouldn't have worked because
the festival script did not pass --script as the first command line
argument as festival.naked requires when running a script. Fixed
by pointing the #! lines directly at the festival.naked binary.
