Fix string/tester.c for GCC 7 -Wstringop-overflow=.
GCC 7 has a -Wstringop-overflow= warning that includes warning for strncat with a size specified that is larger than the size of the buffer (which is dubious usage, but valid at runtime if in fact there isn't an overflow with the particular buffer contents present). string/tester.c tests such cases; this patch arranges for this warning to be ignored around relevant strncat calls. Tested compilation for aarch64 (GCC mainline) with build-many-glibcs.py; did execution testing for x86_64 (GCC 5). * string/tester.c (test_strncat): Disable -Wstringop-overflow= around tests of strncat with large sizes.
