linux-yocto-custom: provide defconfig guidance

As reported by Andrea, defconfigs created with savedefconfig should specify
their expansion mode as "--alldefconfig' for custom yocto recipes. To ensure
that this is documented, we can add a comment in the skeleton recipe.

+#              If the defconfig file was created with make_savedefconfig, 
+#              not all options are specified, and should be restored with their
+#              defaults, not set to 'n'. To properly expand a defconfig like

+#              recipe.
