build: Rework version generation; don't allow make version override

Convert the script to generate the build version from a shell script
to a python script.

Remove the ability to override the version at build time via "make
VERSION=xyz".  Replace it with ability to add extra version
information at build time via "make EXTRAVERSION=xyz".
