Remove distPath logic

This commit purges all distPath logic, going to use System.paths instead
to point to the bundle locations, will do this as part of the build in
steal-tools.
Set System.paths for bundles in production

When the env === "production", set up the default bundles paths so that
they will be found in their dist directory.
