test: ensure /etc/pki/tls/cert.pem exists for 802 tests on EL10

https://issues.redhat.com/browse/RHEL-87511

The `system_ca_certs: true` flag in NM tells wpa_supplicant to load the
legacy single‑file CA bundle (historically at /etc/pki/tls/cert.pem).
Under CentOS Stream 9 (and RHEL 8), that path existed (either as a file
or a symlink to the bundle), so the default “system” loading worked.

On CentOS Stream 10 (RHEL 10), Red Hat switched to a hashed directory
trust store and removed `/etc/pki/tls/cert.pem` to optimize OpenSSL
performance as indicated in
https://docs.redhat.com/en/documentation/red_hat_enterprise_linux/10-beta/html/10.0_beta_release_notes/removed-features
and https://issues.redhat.com/browse/RHEL-50293. wpa_supplicant's
"system_ca_certs" code still tries the old cert.pem path, sees
"No such file or directory" and aborts the TLS setup:

```
OpenSSL: tls_connection_ca_cert - Failed to load root certificates - No such file or directory
EAP‑TLS: Failed to initialize SSL.
```

Hence `system_ca_certs: true` silently fails on Stream 10 because
there is no longer a single‑file CA bundle at that location.

The new ansible-lint does not like variables in play names.
