Add a consistent suffix to all sts poc binaries

This will allow the sts to pass ValidateTestsAbi#testBinariesAbis

Bug: 178631794
Test: make sts # ensure every sts poc ends in _sts32 or _sts64
Test: ensure no tests override the default suffix
Test: source build/envsetup.sh; cd cts/hostsidetests/securitybulletin/securityPatch; mgrep suffix
Test: make cts && cts-tradefed run cts-unit-tests
