limit _shipped to c h and S files

limit _shipped to c h and S files

_shipped targets are intended for generated source files which should not permit .o binary blobs which is currently the case. This patch simply restricts _shipped targets to .c, .h and .S files.

A special case for .inc_shipped is added to prevent breaking drivers/net/wan/wanxlfw.inc_shipped which is a historic "firmware" and can not be reasonably moved to to a loadable firmware.

This patch is against linux 3.18.0-rc1
