Following commit f3de1cf621f7 ("selftests/bpf: sockmap_listen cleanup: Drop
af_unix redir tests") and commit 9266e49d608c ("selftests/bpf:
sockmap_listen cleanup: Drop af_vsock redir tests"), sockmap_listen.c:
family_str() becomes functionally identical to select_reuseport.c:
family_str(). Move the logic to socket_helpers.h.
