Alan Coopersmith 5aabd288ad build: update _XOPEN_SOURCE setting for modern Solaris & illumos 
Previously the build was requesting interfaces matching SUSv1/Unix95,
as implemented in Solaris 2.6 and later.  This changes it to try the
most recent version supported, and limits to the versions supported
by OS versions that meson supports.  This includes these _XOPEN_SOURCE
versions:

800 (2024): supported by illumos starting in July 2024
700 (2008): supported by Solaris 11.4 & illumos from 2014-2024
600 (2001): supported by Solaris 10-11.3 & illumos prior to 2014
