tc, xdp, socket_filter and flow_dissector programs can no longer update
or delete a sockmap. Adjust the tests:
- verifier_sockmap_mutate: the tc, xdp, socket_filter and
flow_dissector cases now expect __failure with "cannot update sockmap
in this context".
- sockmap_basic: drop "sockmap update" / "sockhash update", which load
a SEC("tc") program that copies a sock between maps.
- fexit_bpf2bpf: drop "func_sockmap_update", whose freplace program
updates a sockmap in the tc cls_redirect context.
Remove the now-unused test_sockmap_update.c and freplace_cls_redirect.c.
