make: Remove the Linux datapath.

Update the necessary make and configure files to remove the Linux
datapath and then remove the datapath.

Move datapath/linux/compat/include/linux/openvswitch.h to
include/linux/openvswitch.h because it is needed to generate header
files used by the userspace switch.

Also remove references to the Linux datapath from auxiliary files
and utilities since it is no longer supported.
