Checkmk Werk 13129: set correct access rights on Linux TGZ data structure

ID: 13129 Title: set correct access rights on Linux TGZ data structure Component: agents Level: 1 Class: Bug fix Version: 2.1.0i1 This is a regression since Werk #10429. With Werk #10429, it was prevented that the Linux TGZ package overwrites access rights of existing directories. However, this fix only works for 1.6 releases, while unfortunately it does not take effect in Checkmk 2.0 releases. Therefore the desired behavior is supplied with this Werk.
