Subject: [RFC bpf-next 1/5] libbpf: Add map definition struct fields from iproute2

The iproute2 bpf headers define four more fields for map definitions than
libbpf does. This adds those fields to the libbpf headers, in preparation
for porting the bpf loading functionality of iproute2 to be based on
libbpf. Subsequent commits add the functionality needed in libbpf to be
able to port over iproute2.
