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.

I saw a new expr failure on rootfs this morning testing with this patch,
I have to dig into it to figure out what went wrong.
Sau!
