cr50: change DEV to DBG in debug images version strings

There are two types of signing of CR50 images - prod and dev.
Designating images built with CR50_DEV variable set in the environment
as DEV is confusing, as this has nothing to do with the signing type
(dev vs prod), and is in fact indicating an image with many debug
features enabled.

This patch changes the string to "DBG".

BRANCH=cr50
BUG=none

TEST=verified that the modified image has correct string in the
     version field:
