Unify tidy up logs in lib/img-functions

Cleaning logs was split, some was done in the
img-functions.finalise_base, some was done in the base element.
The version unifies tidy up logs in the lib/img-functions.
Especially when building docker container images the base element
cannot be used. This patch removes about some hundreds KB of
useless logs in cases when the base element is not used.
