Jenkinsfile: allow all ppc64le / s390x stages through checkbox

Previously, the ppc64ls and s390x stages only ran on non-PR commits,
but the unit-tests and integration/xx tests could be enabled with
a checkbox.

This patch changes the Jenkinsfile to also allow the integration-cli
tests to be run on pull requests if the checkbox is enabled.
