    selftests/bpf: Initialize tc in xdp_synproxy
    
    [ Upstream commit 354bb4a0e0b6be8f55bacbe7f08c94b4741f5658 ]
    
    xdp_synproxy/xdp fails in CI with:
    
        Error: bpf_tc_hook_create: File exists
    
    The XDP version of the test should not be calling bpf_tc_hook_create();
    the reason it's happening anyway is that if we don't specify --tc on the
    command line, tc variable remains uninitialized.
