Add tests to set TCP sockopt TCP_BPF_SOCK_OPS_CB_FLAGS via
bpf_setsockopt() and use a cgroup/getsockopt program to retrieve
the value to verify it was set.

Ensures that whenever bpf_setsockopt() is called with the SOL_TCP
option on a ktls enabled socket, the call will be accepted by the
system. The provided test makes sure of this by performing an
examination when the server side socket is in the CLOSE_WAIT state. At
this stage, ktls is still enabled on the server socket and can be used
to test if bpf_setsockopt() works correctly with linux.
