python/semanage: do not show "None" levels when using a non-MLS policy

Browse source 
When MLS is disabled, "semanage export" shows records such as:

    login -a -s sysadm_u -r 'None' me

Prevent "semanage export" from displaying None or empty strings in level
and categories arguments by checking them in all customized() methods.
