Send KEY_LEGTH attribute for ESP ENCR for 3DES. This is invalid and should
be rejected or ignored on the remote side. It requires starting with
--impair-check-keysize which allows specifying bad key sizes.

currently: this is rejected by the other end, but west then sends another
packet which seems to contain garbage:
