target/squashfs: cleanup, remove support for 3.x
Remove the code to build squashfs-tools for the host, since they can now be built using package/squashfs. We also remove support for Squashfs 3.x, because the Squashfs driver merged inside the mainline kernel is a 4.x driver. So 3.x is only useful for old kernels using a Squashfs patch.
