squashfs: add v4.0 support and version selection

Browse Source 
Squashfs 4.0 is needed to create file systems for the mainline squashfs
version (mainline from 2.6.29). This is unfortunately not compatible with
the old 3.x version and the external kernel patches, so add a choice
between the 2 versions.
