kernel-module-split.bbclass: identify kernel modconf files as configuration files

Currently the modconf fragments representing the configuration for
kernel modules are written out to appropriate .conf files and added to
the FILES variable. However they are not identified as 'configuration
files' and installing a new version of a kernel module results in a
conflict and a failed installed because the respective .conf file is
already in place from a previous install.

Add the generated .conf files to the CONFFILES variable denoting their
true nature.
