Makefile.inc: Fix $(@) shows empty issue

When passing $(@) to printf, $(@) is replaced by empty string,
need to add extra '$'.

For example:
  cbfs-files-processor-struct= \
      $(eval $(2): $(1) $(obj)/build.h $(KCONFIG_AUTOHEADER); \
    	# **  @(@) is empty string instead of $(2)   **
    	printf "    CC+STRIP   $(@)  \n"; \
    	# **  $$(@) == $(2)  **
    	printf "    CC+STRIP   $$(@) \n"; \
    ......)
