Update version.version_string to contain packaged version.

This modifies version.version_string to support having the package
build write the *packaged* version in with a easy replace.
Then, when cloud-init reports its version it will include the full
packaged version.

Also modified here are upstream package build files to get that done.

Note part of the trickery in packages/debian/rules.in was to avoid
the 'basic' templater consuming the '$variable' variable names.
