Fix YAML error when lacksK8sScript is true

[funkypenguin]

Fixes the overly-aggressive trimming of whitespace in an if statement, which produced invalid YAML under true condition:

I.e, when lacksK8sScript is true, the deployment would fail a helm lint as follows:

helm lint .
==> Linting .
[INFO] Chart.yaml: icon is recommended
[ERROR] templates/deployment.yaml: unable to parse YAML: error converting YAML to JSON: yaml: line 70: did not find expected key

Error: 1 chart(s) linted, 1 chart(s) failed
