proto: Fix wrong token in proto_icmp6

'token' value of ICMP6HDR_MTU field must be 'mtu', not 'packet-too-big'.
This went unnoticed because rule delinearization for icmp/icmpv6 payload
expressions is problematic anyway in that different fields point to the
same offset and therefore are indistinguishable. In this case, an
expression like e.g. 'icmpv6 mtu 1500' will be printed later as 'icmpv6
parameter-problem 1500'.
