Hi All.

The patch 5c069b6dedef "selftests: Move test output to diagnostic lines" from Apr 24, 2019,

leads to `make run_tests -C bpf` hanging forever.

Bpf includes many subtest, when cmd `make run_tests -C bpf` runs to test_lwt_seg6local.sh, task will hang and runner.sh never run next task. I checked ps aux, prefix.pl will never exit.

Ignore test_lwt_seg6local and run `make run_tests -C bpf` again, task will hang on test_tc_tunnel.sh.

Kushwaha also meet this issue, `make run_tests -C bpf` hang on test_lwt_ip_encap.sh (This test failed on my localhost).
