Disable -Wstringop-overread for some string tests
Similarly to Maciej's changes to fix the build of rawmemchr in the
presence of GCC 11's -Wstringop-overread, also disable that option in
two string function tests that have similar warnings and other string
function warnings already disabled.
Tested with build-many-glibcs.py for aarch64-linux-gnu and
arm-linux-gnueabi that it fixes building the glibc testsuite.
