This function will return a value of the gnutls_sign_algorithm_t
enumeration that is the signature algorithm that has been used to
sign this certificate.
Since 3.6.0 this function never returns a negative error code.
Error cases and unknown/unsupported signature algorithms are
mapped to GNUTLS_SIGN_UNKNOWN.
