build_system: Extend site-local

- Add a target at the end of the build that can be used to run additional
    scripts or additional targets after coreboot.rom is built.
    - Source a site-local Kconfig file to allow site-specific configuration.

This eliminates the need to add a hook for a script at the end of the
    build because you can add one yourself in site-local.

Example site-local/Makefile.inc:

build_complete::
    ifeq ($(CONFIG_SITE_LOCAL),y)
    	echo "Running additional steps in site-local"
    	# run some script here to make my build unreproducible.
    endif

.phony: build_complete

Example site-local/Kconfig:

menu "site-local"

config SITE_LOCAL
    	bool "site-local enabled"
    	help
    	  Enable my site-local configuration to do stuff.

endmenu
