add kernel config locations for fedora and atomic

**What this PR does / why we need it**:

* Fedora stores its kernel configs in /usr/lib/modules/$(uname -r)/config
* Fedora/CentOS/RHEL atomic hosts use /usr/lib/ostree-boot/$(uname -r), though this location is deprecated
* The lack of these locations in the validator is causing kubeadm to hang on "failed to parse kernel config" in its preflight checking on fedora and atomic host

**Special notes for your reviewer**:
