Reenable the standard Perl::Critic policy Modules::RequireExplicitPackage
Modules::RequireExplicitPackage is currently disabled because of :xtest scripts with the extension *.t. Reenable the policy. Probably need to tell Perl::Critic that *.t files are scripts. Also tweak OTOBO::RequireTrueReturnValueForModules to skip validation for *.t scripts.
