[oe] [PATCH] squashfs-4.0: update squashfs-tools to include upstream LZMA inclusion.

[Leon Woestenberg]

In OpenEmbedded we used squashfs 4.0 with external patch for LZMA
compression support. In the meantime, squashfs has mainlined LZMA
support in its CVS version.

This patches switches to the upstream squashfs-tools and modifies
bitbake.conf to match the slightly different arguments to mksquashfs.
