libstdc++: Fix FAIL: 20_util/ratio/operations/ops_overflow_neg.cc [PR122168] 

This backports the additional dg-error added by r15-3859-g63a598deb0c9fc
which is now also needed on gcc-14 due to r14-12048-g9c3777e9619ad3
having been backported.

libstdc++-v3/ChangeLog:

	PR libstdc++/122168
	* testsuite/20_util/ratio/operations/ops_overflow_neg.cc: Add
	dg-error for additional error seen with -Wsystem-headers.
