When building compressed (lzop, gzip) multi-dtb fit images, the compression tool may embed the time or umask in the image.
Work around this by manually setting the time of the source file using SOURCE_DATE_EPOCH and a hard-coded 0600 umask.
With gzip, this could be accomplished by using -n/--no-name, but lzop has no current workaround:
