[PATCH] Finish job of trimming ".o" module extension in Kconfig files

Most of the instances of <module>.o in Kconfig files have had the ".o"
extension trimmed.  This change came from GertJan Spoelman through Rusty
"Trivial" Russell.

However, there are a few files that didn't get trimmed.  This brings
them line with the rest of the tree.
