selftests/bpf: Make sure bpf_{g,s}et_retval is exposed everywhere
For each hook, have a simple bpf_set_retval(bpf_get_retval) program
and make sure it loads for the hooks we want. The exceptions are
the hooks which don't propagate the error to the callers:
- sockops
- recvmsg
- getpeername
- getsockname
- cg_skb ingress and egress
