test: Fix profile assertion on Fedora 33

The NetworkManager in Fedora 33 does not use ifcfg-rh plugin by default,
the CI will fail on Fedora 33 with:

```
TASK [assert that profile 'bond0' is present] **********************************
task path: /tmp/tmpaz9m374e/tests/playbooks/tasks/assert_profile_present.yml:4
fatal: [/cache/fedora-33.qcow2]: FAILED! => {
    "assertion": "profile_stat.stat.exists",
    "changed": false,
    "evaluated_to": false,
    "msg": "profile /etc/sysconfig/network-scripts/ifcfg-bond0 does not exist"
}
```

Previously, we are checking the existence of
`/etc/sysconfig/network-scripts/` to determine whether ifcfg-rh plugin
is enabled. This is incorrect on Fedora 33.

The fix is checking the FILENAME[1] used for storing the NetworkManager
connection, the profile is considered as exists when it exists and does
not contains `/run`.

Since we cannot tell which provider we are using, we just check both
initscripts files and NetworkManager connections.
