Remove weekly images older than 45 days

Weekly images are aimed for manual testing to make sure point releases are sane. Having older images has little sense and consumes lot of storage.

In order to have a better balance between image availability and storage remove weekly images older than 45 days. The value of 45 days was chosen to match half a quarter since Apertis is released on quaterly basis.

Having older images has little sense, since due to the evolution of the distribution many parts change.
