Replace obsolete AC_AIX with AC_USE_SYSTEM_EXTENSIONS

Since Autoconf 2.62 the AC_AIX macro has been made obsolete and should
be replaced with the AC_USE_SYSTEM_EXTENSIONS instead.

Both macro behaviors are the same since the old one is just a wrapper
around the new AC_USE_SYSTEM_EXTENSIONS:

PHP 7.2+ and the main configure.ac script require minimum Autoconf 2.64+.
