fd0ad6f1d1 selftests/bpf: fix a few clang compilation errors 
With latest clang, I got the following compilation errors:
  .../prog_tests/test_tunnel.c:291:6: error: variable 'local_ip_map_fd' is used uninitialized
     whenever 'if' condition is true [-Werror,-Wsometimes-uninitialized]
       if (attach_tc_prog(&tc_hook, -1, set_dst_prog_fd))
            ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
  .../bpf/prog_tests/test_tunnel.c:312:6: note: uninitialized use occurs here
        if (local_ip_map_fd >= 0)
            ^~~~~~~~~~~~~~~
  ...
  .../prog_tests/kprobe_multi_test.c:346:6: error: variable 'err' is used uninitialized
      whenever 'if' condition is true [-Werror,-Wsometimes-uninitialized]
        if (IS_ERR(map))
            ^~~~~~~~~~~
  .../prog_tests/kprobe_multi_test.c:388:6: note: uninitialized use occurs here
        if (err) {
            ^~~

This patch fixed the above compilation errors.

1ee7efd40a selftests/bpf: Move vxlan tunnel testcases to test_progs 
Move vxlan tunnel testcases from test_tunnel.sh to test_progs.
And add vxlan tunnel source testcases also. Other tunnel testcases
will be moved to test_progs step by step in the future.
Rename bpf program section name as SEC("tc") because test_progs
bpf loader could not load sections with name SEC("gre_set_tunnel").
Because of this, add bpftool to load bpf programs in test_tunnel.sh.
