packaging: move version derivation to run_wix_packaging()
With the previous commit moving signing inline, we no
longer need to compute the version string in build_installer()
and can instead move this logic to run_wix_packaging(). This
makes the logic in build_installer() simpler, which makes it
easier to implement alternate building mechanisms.
