Pinning salt:version (previous commit) writes the running version into
salt_settings.version, but the _mapdata reference files are static and one
per OS — shared across the -3006/-3007/-master suites — so they can't carry a
per-image version. Drop salt_settings.version from both sides of the compare:
it now tracks the kitchen image's salt rather than a fixed default, so it's
not a value the static reference should assert.
