selftests/bpf: Drop tc/xdp/flow_dissector/socket_filter sockmap mutation tests

Browse source

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.
