selftests/bpf: BPF_PSEUDO_FUNC reference to the main program
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.
