test: do not use true test with select

Do not use `select("true")`.  This causes an error with Ansible 2.9
with Jinja 2.7 because there is no `true` test.  Instead, just rely
on the default behavior of `select` to evaluate the argument in a
boolean context.

https://jinja.palletsprojects.com/en/2.9.x/templates/#select
`If no test is specified, each object will be evaluated as a boolean.`
