usb_updater: option to report image versions

Browse Source 
It is sometimes necessary to find out headers' version of a cr50
binary blob. This patch adds this ability.

BRANCH=none
BUG=none
TEST=build the new tool image and try it:
  $ ./extra/usb_updater/usb_updater -b /build/kevin-tpm2/opt/google/cr50/firmware/cr50.bin
  read 524288(0x80000) bytes from /build/kevin-tpm2/opt/google/cr50/firmware/cr50.bin
  RO_A:0.0.8 RW_A:0.0.4 RO_B:0.0.8 RW_B:0.0.4
  $
