build_image: dump debug info when target image is full

Browse Source 
When we run out of space in the target image, it can be unclear that this
is the actual issue.  Detect this case and issue an appropriate warning,
and dump disk usage to help people triage things.

BUG=chromium-os:34167
TEST=`./build_image --board=amd64-generic` passed normally
TEST=`./build_image --board=amd64-generic factory_install` triggered the out-of-space check
