Disable IKE fragmentation, use IP-level fragmentation for iOS
iOS may have a bug where it advertises N(FRAG_SUP) but fails to reassemble
IKE fragments in IKE_AUTH responses. Switching to fragmentation=no forces
the large IKE_AUTH response to be sent as a single UDP packet with IP-level
fragmentation, which iOS's standard IP stack handles correctly.
