Add missing no-modify mode for SwMasterUsrPref::Set* functions

...that erroneously called m_aLayoutConfig.SetModified when called from
SwMasterUsrPref ctor -> SwLayoutViewConfig::Load, and thus caused
m_aLayoutConfig to always be written back to the configuration upon
utl::ConfigManager::storeConfigItems during termination.
