Subject: [PATCH] Increase block size of kernel squashfs image to 128K (#3509)

While mksquashfs uses this value by default, Genimage's default is 4K. This is
far too low value and results in slower kernel load, especially on embedded
boards with a flash drive. Explicitly set it to 128K to generate same images as
in pre-genimage builds.
