Avoid to generate anonymous or internal module

[ksss]

Anonymous or internal modules cannot have their names defined as RBS, so they cannot be used even if they get a name. These should be treated as if the name could not be obtained.

Before

$ rbs prototype runtime "NameError*"
class NameError < StandardError
  include DidYouMean::Correctable

  include ErrorHighlight::CoreExt

  public

  def local_variables: () -> untyped

  def name: () -> untyped

  def receiver: () -> untyped

  private

  def initialize: (*untyped) -> void

  class message   #=> Syntax error: expected one of class/module/constant name, token=`message` (tLIDENT)
    def self._load: (untyped) -> untyped

    public

    def ==: (untyped) -> untyped

    def _dump: (untyped) -> untyped

    def to_str: () -> untyped

    private

    def initialize_copy: (untyped) -> untyped
  end
end

After

$ bundle exec rbs prototype runtime "NameError*"
class NameError < StandardError
  include DidYouMean::Correctable

  include ErrorHighlight::CoreExt

  public

  def local_variables: () -> untyped

  def name: () -> untyped

  def receiver: () -> untyped

  private

  def initialize: (*untyped) -> void
end
