feat: report the node kernel's modules and build configuration

A Proxmox node runs its own kernel under every guest, which makes it the host
where a kernel CVE's preconditions matter most. ProxmoxDriver mixes in
KernelFactsMixin from napalm-device-types and supplies only the transport,
the existing exec path.

Requires napalm-device-types 2.1.0.
