[OE-core][PATCH] kernel-module-split.bbclass: fix kernel modules getting marked as CONFFILES

["Gratian Crisan" <gratian.crisan@ni.com>]

Yi pointed out that commit 1a70a92d1f10 ("kernel-module-split.bbclass:
identify kernel modconf files as configuration files") is
unintentionally adding the actual kernel /lib/modules .ko files to the
CONFFILES variable.

The root cause is the re-use of the 'files' variable in that commit.
Fix it by using a separate variable to keep track of the generated
module .conf files that need to be marked as configuration files.
