Fix BoringSSL alert related test failures

Commit bd990e25 changed our handling of alerts. Some of the BoringSSl
tests were expecting specific errors to be created if bad alerts were sent.
Those errors have now changed as a result of that commit, so the BoringSSL
test config needs to be updated to match.
