Re: [libvirt] [PATCH 2/3] qemu: Disallow usage of luks encryption if aes secret not possible

Resolves a CI test integration failure with a RHEL6/Centos6 environment. In order to use a LUKS encrypted device, the design decision was to generate an encrypted secret based on the master key. However, commit id 'da86c6c' missed checking for that specifically. When qemuDomainSecretSetup was implemented, a design decision was made to "fall back" to a plain text secret setup if the specific cipher was not available (e.g. virCryptoHaveCipher(VIR_CRYPTO_CIPHER_AES256CBC)) as well as the QEMU_CAPS_OBJECT_SECRET. For the luks encryption setup there is no fall back to the plaintext secret, thus if that gets set up by qemuDomainSecretSetup, then we need to fail. Also, while the qemuxml2argvtest has set the QEMU_CAPS_OBJECT_SECRET bit, it didn't take into account the second requirement that the ability to generate the encrypted secret is possible. So modify the test to not attempt to run the luks-disk if we know we don't have the encryption algorithm.
