From: SeongJae Park <sjpark@xxxxxxxxx>
Deletions of configs in the '.kunitconfig' is not applied because kunit
rebuilds '.config' only if the '.config' is not a subset of the
'.kunitconfig'. To allow the deletions to applied, this commit modifies
the '.config' rebuild condition to addtionally check the modified times
of those files.
