fix test failures on Solaris 8

[Bruno Haible]

In a gettext build on Solaris 8, I'm seeing 5 test failures:

  FAIL: test-mbrtowc4.sh
  FAIL: test-mbsrtowcs4.sh
  FAIL: test-mbsstr3.sh
  FAIL: test-setlocale1.sh
  FAIL: test-wcrtomb.sh

The reason for these failures is that when LC_ALL is set to zh_CN.GB18030,
the test programs (which are libtool wrapper scripts which invoke the real
programs) misbehave. In particular they fail to set LD_LIBRARY_PATH, leading
to errors like
  ld.so.1: test-setlocale1: fatal: libgettextlib-0.18.1.so: open failed: No 
such file or directory

Narrowing it down: the following command dumps core.
  $ LC_ALL=zh_CN.GB18030 bash -c true
And gdb shows a crash inside a shared library for GB18030. Most likely
related to the Solaris 8 bug that we already test for in m4/mbrtowc.m4.

The fix is to avoid using that broken locale on Solaris 8.

        locale-zh: Reject zh_CN.GB18030 locale on Solaris 8.
        * m4/locale-zh.m4 (gt_LOCALE_ZH_CN): On Solaris 8, set LOCALE_ZH_CN to
        'none'.
