Ignore RSpec/FilePath for this spec

The spec filename does not match the module/class name. But ignore it, because
the `ee` subdir is added in between to avoid conflicts when merging from CE.

spec/lib/gitlab/ee/visibility_level_spec.rb

 require 'spec_helper'
 
-describe Gitlab::VisibilityLevel, lib: true do
+describe Gitlab::VisibilityLevel, lib: true do  # rubocop:disable RSpec/FilePath
   describe '.levels_for_user' do
     it 'returns all levels for an auditor' do
       user = build(:user, :auditor)
