squashfsTools: 4.4 -> 4.5
I had to update the 4k alignment patch for this. While it does apply,
and the result compiles, and even appears to work fine superficially,
I do not know if there have been any changes to squashfs internals that
now require other places to take the alignment flag into account. Will
do more testing soon.
