tests: Fix compilation failure on msys2-mingw64

Philip Withnall requested to merge wip/pwithnall/2565-array-preprocessor into main

This is a follow-up from commit 995823b9, which added the condition

to the array test. On most platforms, both of those symbols are numeric literals, but on 64-bit Windows G_MAXSIZE includes some widening casts, which means it can’t be used in a preprocessor condition.

We don’t expose an appropriate symbol in glibconfig.h which could be used instead, but the standard *_WIDTH symbols from limits.h will be identical and can be used instead.
