[5.5] Fix cache repository (#26497)

* Fix a bug with PHP 7.2.12

PHP 7.2.12 broke the way Carbon's diffInSeconds method works. Using diffInRealSeconds instead fixes the problem.

See briannesbitt/Carbon#1503

* Clean up diff check in cache repository

We can pass the duration here directly.

* Upgrade minimum Carbon requirement

We need this for the diffInRealSeconds method.
