The attach mode is by default set to XDP_MODE_NATIVE and needs to be
overwritten to XDP_MODE_SKB when '-S' option is used. Instead of
overwriting the attach mode was ORed and so was always running in NATIVE
mode. This patch fixes that.

Old system include headers don't have they SO_PREFER_BUSY_POLL and
SO_BUSY_POLL_BUDGET socket option defines. Add conditional defines to the
AF_XDP-example userspace code so we can still compile if they are missing.
Fixes#76.

Move the xdpsock sample application from the Linux repo to the
bpf-examples repo. This example demonstrates a number of capabilities
of AF_XDP sockets.
