ContainerFactory::clearOldContainers check only ctime, not atime

• When cache is pulled from some storage (e.g. S3), it gets recent atimes and this does not work. That causes unwanted cache swelling.

I don't think this is a great fix. Other systems might have problems with different timestamp metadata.

PHPStan should keep some kind of "journal" with real access times for each generated container, and delete them based on that.

Glad you are looking into this! This was pretty major issue in my eyes :) Thanks!
