Jenkins: re-add erroneously removed when build conditions

Debian packages should only be build if a file in the requested subfolder
changes (like a version upgrade) or if explicitly reuested by the user.

VyOS ISO generation should only be run once a night by the CI if triggered by
the timer, or on explicit user request.
