A new release has been made upstream. Reproducibility issues were fixed
in that release, so we no longer need those patches. For a full overview
of the changes, see the 4.4-specific readme at [1].

The alignment patch no longer applies cleanly; I disabled it for now,
and I will try to restore it in a follow-up commit.

[1]: https://github.com/plougher/squashfs-tools/blob/52eb4c279cd283ed9802dd1ceb686560b22ffb67/README-4.4

I took the patch, and applied it on top of the previous squashfs-tools
commit that we packaged (which required editing one line in the patch,
as it assumed to be applied on top of the reproducibility patches). Then
I rebased that on top of master, resolved one conflict, and I formatted
a new patch for this.

I took the patch, and applied it on top of the previous squashfs-tools
commit that we packaged. It applied cleanly. Then I rebased that on top
of master, and resolved the conflicts. I'm not sure I resolved them
correctly though, I don't have access to Darwin. Somebody needs to
review this.

This new patch is the patch between 4.4, and commit [1], a pull request
at [2] to upsteam Mac and BSD compatibility. That pull request is
itself a rebase of an older pull request for an earlier version of
squashfs-tools. I squashed all commits between 4.4 and [1], apart from
the BSD-specific ones, and exported the new patch from that. Attached
below is the git diff --ignore-space-change between squashfs-tools 4.4
with the previous patch applied, and with the new patch applied.
