I got some feedback from the kmod upstream, a v2 will be coming soon.

This adds a new configuration directive to depmod that causes
depmod to exclude a give path entry like .debug.
kernel-dbg provides the modules .debug/<module>.ko files and
when installed either directly or when dbg-pkgs are selected
this can cause depmod to fail.
This patch will be submitted to upstream kmod.

+Subject: [PATCH] depmod: Add support for excluding a directory
+
+This adds support to depmod to enable a new exclude directive in
+the depmod.d/exclude.conf configuration file. Currently depmod
+already excludes directories named source or build. This change
+will allow additional directories like .debug to be excluded also
+via a new exclude directive.
+
+depmod.d/exclude.conf example:
+exclude .debug
