Hanshake serialization requires that the selected ciphersuite uses an AEAD algorithm. However, following the DHE-RSA removal, trying to still use RSA signature might select a ciphersuite which is not using AEAD, but CBC instead (see preference order in "ssl_ciphersuite.c"). This is especially problematic in tests scenarios where both GCM and ChaChaPoly are disabled, so that CCM remains as the only AEAD algorithm. Ciphersuites using RSA signature and CCM are very low on the preference list, so very unlikely to be picked in tests. This cause a CBC one to be selected in this case and the handshake_serialization() function to fail. In order to prevent failures from happening, in this commit we require that either GCM or ChaChaPoly are enabled, so that ciphersuites using one of these are likely to be picked.
