Note: ip/ipvrf.c is not convert to use libbpf as it only encodes a few
instructions and load directly.

for completeness, libbpf should be able to load a program from a buffer
as well.

It can, but the particular use in ipvrf is just loading half a dozen
instructions defined inline in C - there's no object files, BTF or
anything. So why bother with going through libbpf in this case? The
actual attachment is using the existing code anyway...
