Add a test case for a BPF_PSEUDO_FUNC load instruction that references the entry function of the program it belongs to. W/o the previous patch the verifier accepts this program thus allowing a runtime call at a bogus address. See previous patch for detailed description. Main function needs to be marked with BTF_FUNC_STATIC for the test to trigger the bug, the patch uses test_verifier harness instead of test_prog because libbpf has no way to convey this.
