selftests/bpf: test_tunnel: Move ip6geneve tunnel test to test_progs

Browse Source 
ip6geneve tunnels are tested in the test_tunnel.sh but not in the
test_progs framework.

Add a new test in test_progs to test ip6geneve tunnels. It uses the same
network topology and the same BPF programs than the script.
Remove test_ip6geneve() from the script.
