VPP-498: Prepare vpp RPM packaging for use by downstream distros.

Change spec to add new macros to get rid of relative dir reference and
use vpp version. Store version string in .version to store metadata in
dist archive. New script to create dist archive.
Add dist and wipedist targets to Makefile for builds of source RPMs.
