Add more information to loopback mount failures.

Buildbots are periodically failing to build images; the evidence
points to failures in mount_gpt_image.sh, but it's inconclusive.
Add detailed error messages to mount failures so as to be able
to debug more the next time it happens.

BUG=chromium-os:24975
TEST=build_image, to see that successful cases still work
TEST=repeatedly mount new images with mount_gpt_image until it fails
