bpf: Fix helpers ctx struct types in uapi doc
Helpers may operate on two types of ctx structures: user visible ones (e.g. `struct bpf_sock_ops`) when used in user programs, and kernel ones (e.g. `struct bpf_sock_ops_kern`) in kernel implementation. UAPI documentation must refer to only user visible structures. The patch replaces references to `_kern` structures in BPF helpers description by corresponding user visible structures.
