Updates using factorio-updater do not work for 2.x

[bioxz]

~~I guess due to a changed package name, using the update function does not work for 2.x~~

Due to a change of the --version output of the binary, updates are not working for the 2.x version.

$ /opt/factorio/factorio-init/factorio update -l

Running updater in --dry-run mode, no patches will be applied

Factorio 1.x prints a Binary version, while 2.x prints just a Version:

Version: 1.1.108 (build 62305, linux64, headless)
Binary version: 64
Map input version: 0.18.0-0
Map output version: 1.1.108-0

Version: 2.0.8 (build 79416, linux64, headless)
Version: 64
Map input version: 1.0.0-0
Map output version: 2.0.8-1

This leads to the 64 missing in the package name.

Running the updater by hand did work (at least from 2.0.7 stable to 2.0.8 experimental). The server-init itself is also still running well.
