Fix tar permisison override

[bimtauer]

TL;DR

This fixes an issue where unpacked fast-registered tar archives end up having d--------- as file permissions. Root doesn't care but we prefer not to run as root. With that line removed, the permissions end up drwx------ which works. uid and gid are overridden when unpacking so that part is no problem.
