closed because it confirms whether the configured limits are actually being
enforced upon login.

The previous test merely validated the serialization of one particular config
in the config file.

* gnu/tests/pam.scm (pam-limits-service): Revise test to confirm limits on
login.
(%test-pam-limits)[description]: Update.
(%test-pam-limits-deprecated): Remove.
