Ensure values are cast to correct type

https://github.com/willshersystems/ansible-sshd/issues/188
This shouldn't be necessary, but there seems no way to
guarantee using a version of Jinja which doesn't have this
problem.

In addition - it is not good practice to compare values to
`true` or `false` - instead, just ensure the value is a `bool`
type and evaluate in a boolean context.
