Mahe Tardy c7838e3dc6 selftests/bpf: Add ksock kfunc test
Add a selftest that exercises the ksock kfuncs end-to-end. One syscall
BPF setup program creates a ksock context and connects the socket.
Another LSM sleepable BPF program looks up the context and send test
data. The userspace harness creates a network namespace and a new socket
on loopback, run the setup syscall prog and send LSM BPF prog then check
that the userspace socket received the data from BPF.
