Fix configure check for %z printf support after INT64_MODIFIER changes.

Browse source 
The PGAC_FUNC_SNPRINTF_SIZE_T_SUPPORT test was broken by
ce486056ec. Among others it made the UINT64_FORMAT macro to be
defined in c.h, instead of directly being defined by configure.

This lead to the replacement printf being used on all platforms for a
while. Which seems to work, because this was only used due to
different profiles ;)

Fix by relying on INT64_MODIFIER instead.
