kata-deploy: export CI in the build container

The clone_tests_repo() in ci/lib.sh relies on CI variable to decide
whether to checkout the tests repository or not. So it is required to
pass that variable down to the build container of kata-deploy, otherwise
it can fail on some scenarios.

Fixes #4949
