Set time and umask on fit-dtb.blob to ensure reproducibile builds.
Support for compressed fit-dtb.blob was added in: commit 95f4bbd5 ("lib: fdt: Allow LZO and GZIP DT compression in U-Boot") When building compressed (lzop, gzip) fit-dtb.blob 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: https://bugs.debian.org/896520 This is essentially the same fix applied to multi-dtb fit SPL images in: commit 8664ab7d ("Set time and umask on multi-dtb fit images to ensure reproducibile builds.")
