set-time-and-umask-on-spl-fit-files

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:
