Ruud van Asseldonk 9c50f53065 squashfsTools: apply reproducibility patches
Without these patches, the output of mksquashfs is not reproducible.
The patches are taken from https://github.com/squashfskit/squashfskit,
a fork of squashfs-tools, licensed under the GPL2 or later like
squashfs-tools itself.
