A subtest setup can fail in a wide variety of ways, so make sure not to
run it if an issue occurs during its setup. The return value is
already representing whether the setup succeeds or fails, it is just
about wiring it.

test_tc_tunnel is missing checks on any open_netns. Add those checks
anytime we try to enter a net namespace, and skip the related operations
if we fail. While at it, reduce the number of open_netns/close_netns for
cases involving operations in two distinct namespaces: the test
currently does the following:
nstoken = open_netns("foo")
do_operation();
close(nstoken);
nstoken = open_netns("bar")
do_another_operation();
close(nstoken);
As already stated in reviews for the initial test, we don't need to go
back to the root net namespace to enter a second namespace, so just do:
ntoken_client = open_netns("foo")
do_operation();
nstoken_server = open_netns("bar")
do_another_operation();
close(nstoken_server);
close(nstoken_client);

test_tc_tunnel currently uses start_reuseport_server because it needs to
frequently start and stop the server, so we need SO_REUSEPORT to avoid
getting errors on server restart due to the socket being in TIME_WAIT
state. But the test is only using one server at a time, so it is a bit
confusing to use this API.
Replace start_reuseport with start_sever_str, and provided the relevant
callback to set SO_REUSEPORT.

I meant to directly enable SO_REUSE"ADDR" in the start_server_addr()
instead of each individual test using SO_REUSEPORT. I think all tcp server
in test_progs should have it enabled. Something like this:
