icmp: fix InterfaceIdent.Index handling

RFC 7223, Section 3 defines 32 bits for if-index.
RFC 8335, Section 2.1 defines
"If the Interface Identification Object identifies the probed
interface by index, the length is equal to 8 and the payload contains
the if-index [RFC7223]."
The object should be comprised of a 4-byte object header and a 4-byte interface index.

Fixes golang/go#28530
