kmod: fix configure with autopoint calling gtkdocize

documentation directory in the GTK_DOC_CHECK call.

+Subject: [PATCH] configure: set docdir in GTK_DOC_CHECK
+
+By passing --docdir in the GTK_DOC_CHECK arguments (to match
+autogen.sh) autoreconf will work out of the box.
+
+Without this autoreconf fails due to the documentation not being in
+./docs, the default location.
