[PATCH] When kmodpy is not available call kmod binary directly

[Michal Suchanek <msuchanek@suse.de>]

kmodpy is an unmaintained project. Python is not really good at
backwards compatibility. With the upstream project not keeping up with
python churn using the library is a maintenance burden.

nvmet does not use the python library in any substantial way, it only
loads a module once. This can be easily accomplished without any library
using the modprobe tool directly.
