Improve error handling with different OpenSSL versions

What does this PR do?

Backports https://github.com/saltstack/salt/pull/66818

With the most recent versions of cryptography module the exception value which is checked here https://github.com/saltstack/salt/blob/246d0664577ef72da8bd1f0c4dff0d18b4428b23/salt/utils/x509.py#L704 is different. The latest version of cryptography is returning https://github.com/pyca/cryptography/blob/932b8a3f67810140a6e178f7b676e1cb9c3585b1/src/rust/src/backend/utils.rs#L463

It could also be returned with the lower version of cryptography depending on the combination with the OpenSSL version it's used with.

Previous Behavior

x509.private_key_managed state function could fail with the comment Could not load PEM-encoded private key The following tests could fail as well:

tests/pytests/functional/states/test_x509_v2.py::test_private_key_managed_passphrase_changed_overwrite
tests/pytests/functional/states/test_x509_v2.py::test_private_key_managed_passphrase_changed_not_overwrite

New Behavior

No test fails and x509.private_key_managed state with most recent cryptography or some other OpenSSL versions which can produce different errors on such cases.
