image.mk: use XZ bcj architecture filter if available
xz supports using an architecture specific BCJ filter, use that one to save us a couple kB while producing squashfs filesystems (mimics the Linux kernel). Signed-off-by: Florian Fainelli <florian@openwrt.org> git-svn-id: svn://svn.openwrt.org/openwrt/trunk@35097 3c298f89-4303-0410-b956-a3cf2f4a3e73
