selboolean provider does not fully manage persistent feature

The provider for selboolean is very limited regarding the persistent parameter:

Puppet will only set a boolean to be persistent if it will also change the current value.

This is because the provider (getseboolean) does not support retrieving the current state of the persistent field.

This has the drawback, that if a boolean is already enabled, but later should also be enabled in a persistent manner, puppet won't do the necessary change and simply skips that task.
