A couple of the syscalls which load values (bpf_skb_load_helper_16() and
bpf_skb_load_helper_32()) are using u16/u32 types which are triggering
warnings as they are then converted from big-endian to CPU-endian. Fix
these by making the types __be instead.
Fixes the following sparse warnings:
net/core/filter.c:246:32: warning: cast to restricted __be16
