Pablo Carranza Velez 9540ed415b Make the base image hash more deterministic
We've been using tar directly on the base image folder, and this makes
the file ordering unpredictable between filesystems, so we use find and
sort so that the files are always tarred in the same order, producing the same
hash in different filesystems.

We also now set the mtime to the specific Unix timestamp 0, to avoid differences
due to timezones.

Also remove the dest folder before calculating the hash.
