Reduce amount of waiting time when running test_progs in parallel mode (-j) by splitting bpf_verif_scale selftests into multiple tests. Previously it was structured as a test with multiple subtests, but subtests are not easily parallelizable with test_progs' infra. Also in practice each scale subtest is really an independent test with nothing shared across all substest. This patch set changes how test_progs test discovery works. Now it is possible to define multiple tests within a single source code file. One of the patches also marks tc_redirect selftests as serial, because it's extremely harmful to the test system when run in parallel mode.
