build_image: print the size of the rootfs
Add the size of the rootfs of the base image to the build log. This
makes it easy to see the rootfs usage from a build log, without having
to download/mount an image and manually check the output of df.
Typical output:
INFO : Usage of the root filesystem:
INFO : Blocks: Total: 579536 Used: 482893 Free: 96643
INFO : Inodes: Total: 147456 Used: 13053 Free: 134403
INFO : Size (bytes): Total: 2373779456 Used: 1977929728 Free: 395849728
INFO : Size (MiB): Total: 2263 Used: 1886 Free: 377
BUG=chromium:1074024
TEST=run build_image, verify that the output shows the expected message
