Limit the scope of fixing permissions

Permissions should only be fixed for mutable data directories, not the Docker image itself.

v2: Change to only ignore node_modules
v3: Throw in some extra restrictions for static content that is part of
    the Docker image
v4: Include .config.js files in the list as necessary
