[PATCH v3] isar-bootstrap: Remove apt-transport-https

["Q. Gylstorff" <Quirin.Gylstorff@siemens.com>]

From: Quirin Gylstorff <quirin.gylstorff@siemens.com>

Since apt 1.5 apt-transport-https is part of apt. This
package is no longer needed. If Debian stretch is used as
distro base re-add apt-transport-https.
