selftests/bpf: Remove unused variable in tc_tunnel prog

Browse source 
The variable buf is unused since commit 005edd1656 ("selftests/bpf:
convert bpf tunnel test to BPF_ADJ_ROOM_MAC"). Remove it to fix the
following warning:

    test_tc_tunnel.c:531:7: warning: unused variable 'buf' [-Wunused-variable]

Fixes: 005edd1656 ("selftests/bpf: convert bpf tunnel test to BPF_ADJ_ROOM_MAC")
