tzcode-native: fix build with gcc-13 on host

Browse Source 
* passing -std=c2x to avoid build failure with gcc-13 on host
  works as well, but the resulting zic then segfaults when
  used in tzdata, use a fix from upstream instead

* reported upstream in https://mm.icann.org/pipermail/tz/2023-March/032690.html

* fixes:

Subject: [PATCH] Fix C23-related conformance bug
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Problem reported by Houge Langley for ‘gcc -std=gnu99’ in:
https://bugs.gentoo.org/show_bug.cgi?id=883719
* NEWS: Mention this.
* date.c, localtime.c, private.h, zdump.c, zic.c:
Use ATTRIBUTE_* at the start of function declarations,
not later (such as after the keyword ‘static’).
This is required for strict conformance to C23.
Upstream-Status: Backport [https://github.com/eggert/tz/commit/9cfe9507fcc22cd4a0c4da486ea1c7f0de6b075f]
NEWS change skipped to avoid conflicts.
