selftests/bpf: Use start_server_str rather than start_reuseport_server in tc_tunnel

Now that start_server_str enforces SO_REUSEADDR, there's no need to keep
using start_reusport_server in tc_tunnel, especially since it only uses
one server at a time.

Replace start_reuseport_server with start_server_str in tc_tunnel test.
