Fixed the input image size when running makeflash.sh

[jsfakian]

• When we create live and installer images with the latest version of master, we make it with less size than necessary. There was a previous commit (719b4d5) that increased the rootfs image size, which also required the corresponding change in the Makefile.

Without this fix 'make live run' would fail.

For instance, currently make live is broken, image generation is failing due to the problems mentioned in the PR:
