Allow the image to be up to 10MB larger than specified.

We ran into a case in the reven-vmtest postsubmit builder where
image_to_vm.sh was failing because the stateful partition on our test
images was 8198MB, while the disk layout specifies 8192MB.

After some investigation we narrowed the issue down to the `fs_align`
attribute in disk_layout_v2.json: without that attribute the stateful
partition comes out as specified.

This change makes image_to_vm.sh more permissive when resizing the
stateful partition: the partition on the image can now be up to 10MB
larger than is specified in the disk layout.
