Ido Schimmel 11604178fd selftests: forwarding: tc_tunnel_key: Make filters more specific

The test installs filters that match on various IP fragments (e.g., no
fragment, first fragment) and expects a certain amount of packets to hit
each filter. This is problematic as the filters are not specific enough
and can match IP packets (e.g., IGMP) generated by the stack, resulting
in failures [1].

Fix by making the filters more specific and match on more fields in the
IP header: Source IP, destination IP and protocol.
