bpf: Convert bpf_sock_addr_kern "uaddr" to sockaddr_unsized
Change struct bpf_sock_addr_kern to use sockaddr_unsized for the "uaddr"
field instead of sockaddr. This improves type safety in the BPF cgroup
socket address filtering code.
The casting in __cgroup_bpf_run_filter_sock_addr() is updated to match the
new type, removing an unnecessary cast in the initialization and updating
the conditional assignment to use the appropriate sockaddr_unsized cast.
Additionally rename the "unspec" variable to "storage" to better align
with its usage.
No binary changes expected.
