bpf: Fix build error without CONFIG_NET
If CONFIG_NET is n, building fails:
kernel/trace/bpf_trace.o: In function `raw_tp_prog_func_proto':
bpf_trace.c:(.text+0x1a34): undefined reference to `bpf_skb_output_proto'
Wrap it into a #ifdef to fix this.
Fixes: a7658e1a4164 ("bpf: Check types of arguments passed into helpers")
