util/cbmem: Fix CBMEM TOC printing

Since commit c0199078 (cbmem utility: Find actual CBMEM area) [1], at least on
the Lenovo X201, X230 and X60, printing the CBMEM table of contents did
not work.  It still worked on the ASRock E350M1 though.

	$ sudo /src/coreboot/util/cbmem/cbmem -l --verbose # Lenovo X60t
	Looking for coreboot table at 0
	Mapping 1MB of physical memory at 0x0.
	Found!
	  coreboot table entry 0x11
	    Found forwarding entry.
	Unmapping 1MB of virtual memory at 0xb74dc000.

	Unmapping 1MB of virtual memory at 0xb74dc000.
	No coreboot CBMEM area found!

The address of the boot info record has to be used for checking, that reading
takes place in the bounds of the boot info record.

	$ sudo ~/src/coreboot/util/cbmem/cbmem -l # Lenovo X60
	CBMEM table of contents:
	    ID           START      LENGTH
	[…]

Big thanks to David and Stefan for their help.
