For reproducible builds the calculation of the filesystem UUID should be persistent with each rebuild of the image. To achieve this the UUID is calculated using the SOURCE_DATE_EPOCH from the environment plus a char-number representation of the filesystem label name as random seed. In kiwi every filesystem is created with a label, thus only in case there is no SOURCE_DATE_EPOCH available we continue to create the UUID as random data. This Fixes #2761
