[PATCH bpf-next 1/4] selftests/bpf: less spam in the log for message matching

[Eduard Zingerman <eddyz87@gmail.com>]

When running test_loader based tests in the verbose mode each matched
message leaves a trace in the stderr, e.g.:

    ./test_progs -vvv -t ...
    validate_msgs:PASS:expect_msg 0 nsec
    validate_msgs:PASS:expect_msg 0 nsec
    validate_msgs:PASS:expect_msg 0 nsec
    validate_msgs:PASS:expect_msg 0 nsec
    validate_msgs:PASS:expect_msg 0 nsec

This is not very helpful when debugging such tests and clobbers the
log a lot.
