Add support for auto-loading modules
As of !114 (merged), it is possible to manually load modules at boot time. This is however a little annoying as we may not know what modules we need to load, so let's add support for auto-loading modules based on the devices modalias.
We can use https://github.com/bensallen/modscan as a base, but I would really like to add this capability directly to u-root so that others may improve on it. Finally, I really think we should add support for hotplugging, as containers can't easily modprobe modules (unless someone decides to add -v /lib/modules
to their podman cmdline!
