Subject: [PATCH] always write to dataDir in the current directory

Now that init can take a directory for configuration, the old behavior
of writing the .terraform data directory into the target path no longer
makes sense. Don't change the dataDir field during init, and write to
the default location.

Clean up all references to Meta.dataDir, and only use the getter method
in case we chose to dynamically override this at some point.
