git-compat-util.h: support variadic macros with the XL C compiler

When the XL C compiler is run with an appropriate language level or
suboption, it defines a feature test macro to indicate support for
variadic macros by defining __C99_MACRO_WITH_VA_ARGS C preprocessor
macro.

This was tested on z/OS, but it should also work on AIX according
to IBM documentation.
