Make sure Import-CliXML can find update_info.xml

[JonasGroeger]

Without this fix, I get

Import-CliXML : Die Datei "D:\Projects\chocolatey-packages\update_info.xml" konnte nicht gefunden werden.
In D:\Projects\chocolatey-packages\au\update_all.ps1:55 Zeichen:21
+ $global:updateall = Import-CliXML $PSScriptRoot\..\update_info.xml

So two changes that affected each other, we need to go over to automatic because we can't tell Update-AUPackages where the directory to process is. Or can we @majkinetor?

No, there is no other way at the moment.
