sharutils: internationalization of shar/unshar doesn't work

[Bruno Haible]

The "internationalized" shar scripts produced by GNU sharutils 4.2.1
actually never cause internationalized messages to be printed when
the script is executed by "sh" or "unshar". There are two bugs:

1. The scripts expects a particular format for "gettext --version",
which is not the format being used.

2. The script uses "shar --print-text-domain-dir", but when a --prefix
has been given, the result is always wrong: it prints /usr/share/locale
but should print $prefix/share/locale.

Here is a fix.

        * shar.c (generate_configure): Less strict test for GNU gettext.
        (main): For --print-text-domain-dir, output the configured LOCALEDIR,
        not the fallback _nl_default_dirname.
