Skip checking files under .../directory-hash/ dir

* The main reason for this change is to improve performance and
reduce flood of logs for the content that does not seem to be important
to check for the upgrade process.

The directory has been relatively recently added to ca-certificates
rpm on EL 9+ systems mostly to improve performance of OpenSSL and
the content does not seem to be important for the IPU process.
The high number of files takes too much time to evaluate and causes
flood of logs that are not important.

This is updated solution that we drop originally: 60f500e
