Add missing notifies for ohai[reload_packages] on Fedora/RHEL

Without this, it doesn't properly run ``installed_rabbitmq_version`` and causes
an error:

```
  * ohai[reload_packages] action nothing (skipped due to action :nothing)
Recipe: rabbitmq::management_ui
  * rabbitmq_plugin[rabbitmq_management] action enable

    ================================================================================
    Error executing action `enable` on resource 'rabbitmq_plugin[rabbitmq_management]'
    ================================================================================

    NoMethodError
    -------------
    undefined method `[]' for nil:NilClass
