Remove the requirement to coordinate between linux-cp and sflow at
build time via cmake. Also, remove 350 lines of awkward thread-forking
VAPI code. Replace it with a dynamically retrieved function from the
linux-cp plugin, called lcp_itf_pair_get_vif_index_by_phy().
Remove build inhibit based on Netlink headers, and only inhibit the
build for FreeBSD. This plugin can now run regardless of Linux CP
being built or loaded, and then return VPP ifIndex numbers instead.
Also, fix a flaky test where non-ephemeral source ports throw off
packet captures.

1) we rely on Netlink PSAMPLE and USERSOCK make sure we have headers
2) sflow plugin is not available on FreeBSD, due to Netlink features
3) preprocessor flag SFLOW_USE_VAPI controls whether the sflow plugin
will attempt to contact the linux-cp plugin using the binary VAPI. It
has to be a preprocessor flag so it can suppress the "#include"
statements that define that linux-cp api, because those include files
will be missing if linux-cp is excluded from the build.
The "excluded_plugins" list can be used with:
make VPP_EXCLUDED_PLUGINS=linux-cp build build-release

This is an sFlow dataplane plugin that can sample
1-in-N packets from device-input, copying them to
a FIFO queue and servicing that queue from a main
process which formats them as Netlink PSAMPLEs,
to be picked up by a popular sidecar agent called
host-sflow.
