kernel-module-split: make autoload and probeconf distribution specific

The modules-load.d [1] - Configure kernel modules to load at boot
should install their configuration files in /usr/lib/modules-load.d.

The modprobe.d [2] - Configuration directory for modprobe
should install their configuration files in /lib/modprobe.d
