gmp: Make sure the modulus is odd and the exponent not zero
Unlike mpz_powm() its secure replacement mpz_powm_sec() has the additional
requirement that the exponent must be > 0 and the modulus has to be odd.
Otherwise, it will crash with a floating-point exception.
Fixes: CVE-2017-9022
Fixes: 3e35a6e7a1b0 ("Use side-channel secured mpz_powm_sec of libgmp 5, if available")
