busybox: Exclude .debug from depmod

As with the kmod version of depmod, exclude .debug from being

configuration file option is ignored we just hardcode it.

+The .debug/<module>.ko files do not have the correct symbol information
+since it's split away from the actual <module>.ko file. Just ignore it.
