netfilter: xt_bpf: add mising opaque struct sk_filter definition
commit e10038a8ec06ac819b7552bb67aaa6d2d6f850c1 upstream.
This structure is not exposed to userspace, so fix this by defining
struct sk_filter; so we skip the casting in kernelspace. This is safe
since userspace has no way to lurk with that internal pointer.
Fixes: e6f30c7 ("netfilter: x_tables: add xt_bpf match")
