crypto: Define MODP_CUSTOM outside of IKE DH range

Before this fix it was possible to crash charon with an IKE_SA_INIT message containing a KE payload with DH group MODP_CUSTOM(1025). Defining MODP_CUSTOM outside of the two byte IKE DH identifier range prevents it from getting negotiated. Fixes CVE-2014-9221.
