Project: Add build version to CFBundleVersion

[russellhancox]

This adds the current build version as the final component of the CFBundleVersion (e.g. 2022.2.429612858) and includes the build version in santactl version output:

santad          | 2022.2 (build 429612858)
santactl        | 2022.2 (build 429612858)
SantaGUI        | 2022.2 (build 429612858)

The CFBundleShortVersionString remains the "product" version to match GH releases. I did not add the build version to the kernel extension as the version formatting there is much more strict and we're likely removing it before the next release anyway.
