Fix CryptoTestUtilsTest.
Fix CryptoTestUtilsTest.

CryptoTestUtilsTest.TestGenerateFullCHLO picks the first version with
PROTOCOL_QUIC_CRYPTO, but ShloVerifier.ValidateClientHelloDone() uses
AllSupportedVersions().front() and assumes it is the same version.  In order to
fix it, this CL pumbs the version through ShloVerifier.

This is prework for cl/290840338.
