selftests/bpf: Use local type for flow_offload_tuple_rhash in xdp_flowtable

Browse Source 
Define flow_offload_tuple_rhash___local and use it in place of the
forward-declared kernel type for the bpf_xdp_flow_lookup kfunc return
type and tuplehash variable. This is consistent with how
bpf_flowtable_opts___local is already handled in the same file and
avoids relying on a forward declaration of the struct.
