Some distributions aim at not shipping any files in / outside of usr.
The path under which kernel modules are installed is hardcoded to /lib
which conflicts with this goal.
When kmod provides the config command, use it to determine the correct
module installation prefix.
This is a prefix under which the modules are searched by kmod on the
system, and is separate from the temporary staging location already
supported by INSTALL_MOD_PATH.
With kmod that does not provide the config command empty prefix is used
as before.
