Swupd used to use a sorted blob of extended file attributes as part of the data that was used to verify the contents. This caused problems if extra attributes were added. In particular if a clearlinux system was being run in a container that had selinux enabled in the base OS. Add a configure option to allow the attributes to be considered or not. Based on advice, the default is to ignore them, as this is what everyone expects. Tidied up passing a --selinux flag to tar, this is also handled by a new config option.
