testsuite: add -Wno-overflow to avoid warning in test [PR123191]

Without -Wno-overflow, for arm-none-eabi targets, I see warnings like:
coreutils-group_number.c:13:21: warning: conversion from 'long long unsigned int' to 'size_t' {aka 'unsigned int'} changes value from '18446744073709551615' to '4294967295' [-Woverflow]

gcc/testsuite/ChangeLog:

	PR testsuite/123191
	* c-c++-common/analyzer/coreutils-group_number.c: Add
	-Wno-overflow.
