lualoader: Simplify some expressions

- No need for a 'goto' when our entire loop body is then wrapped in a
  conditional.

- No need to leave commented out prints laying around

- If an expression is clearly going to be either nil or an expression that
  isn't likely to be a boolean, we might as well use `or` to specify a
  default value for the expression. e.g. `loader.getenv(...) or "no"`
