util/chromeos/crosfirmware: Fix handling of newer boards 

Wile historically there was a unique recovery image for each Chrome OS
board/HWID (with matching names), this is no longer the case. Now,
multiple boards share a single recovery image, so adjust how the proper
recovery image is determined, and how the coreboot image is extracted from it.

Test: successfully extract coreboot images for older 1:1 boards (e.g. CAVE)
and newer 1:N boards (e.g. DROBIT)
