[PATCH V3 1/1] image_types.bbclass: Round up ROOTFS_SIZE after base_size check

[Andrei Gherzan]

If we round up ROOTFS_SIZE to IMAGE_ROOTFS_ALIGNMENT before checking if
base_size is greater then IMAGE_ROOTFS_SIZE, we can end up adding an
unaligned value to IMAGE_ROOTFS_SIZE. Obviously, if
IMAGE_ROOTFS_EXTRA_SPACE was overwritten with an unaligned value. So
let's add the round up code after the base_size calculus and it's
comparison.
