Check_MK Werk 6937: Agent Updater: Make executable format rule optional again

ID: 6937 Title: Agent Updater: Make executable format rule optional again Component: agents Level: 1 Class: Bug fix Version: 1.6.0i1 Regression since Werk 6934: With Check_MK 1.5.0p10, baking agents would fail if the rule "Executable format (Linux)" is not set within the Agent Updater ruleset. Since this rule is intended to be optional, this werk restores the normal behavior. As a workaround for 1.5.0p10, please set the rule to "64bit packaged binary" to obtain the default setting and make the agents bakeable again.
