cbfstool: Use cbfs_image API for "locate" command.

Browse Source 
To support platforms without top-aligned address mapping like ARM, "locate"
command now outputs platform independent ROM offset by default.  To retrieve x86
style top-aligned virtual address, add "-T".

To test:
	cbfstool coreboot.rom locate -f stage -n stage -a 0x100000 -T
	# Example output: 0xffffdc10
