The binaries consumed from upstream should have the same checksums already but the resulting squashfs does not because it contains the time stamps of the build. Define the SOURCE_DATE_EPOCH variable which is enough to make mksquashfs reproducible. The user can pass an own value if there is a fixed reference time. For semantics, see https://reproducible-builds.org/docs/source-date-epoch/ Fixes #25
