lib,daemon: add cgroup_sock_addr hooks, flavor, and BPF type constants
Add BF_FLAVOR_CGROUP_SOCK_ADDR and BF_HOOK_CGROUP_SOCK_ADDR_CONNECT4/CONNECT6 to support BPF_PROG_TYPE_CGROUP_SOCK_ADDR programs. This is the foundational enum/mapping work for sock_addr filtering. All mapping tables (hook strings, flavor, prog_type, attach_type), BPF type constants, and hookopts are updated. All existing packet-based matchers are blocked on the new hooks via unsupported_hooks. Flavor ops are registered as NULL and codegen is added in a follow-up.
