util/cbfstool: Decouple elogtool from vboot_ref flashrom code

Currently elogtool sub-proccesses flashrom as calling libflashrom
requires a missing function from the previous flashrom release.
Pending a new release of flashrom we must continue to use subprocess.

However the current subprocess wrapper implementation lives in
vboot_reference which is a git sub-module of coreboot. This causes
all sorts of grief keeping a subprocess ABI stable from vboot_reference
when the rest of vboot_reference builds of HEAD of the flashrom tree
(i.e., using unreleased libflashrom functions). In order to not keep
finding ourseleves in a bind between the two separately moving trees
with different build environments, decouple elogtool with its own
mini copy of flashrom subprocess wrapping logic.

Squash in,
 util/cbfstool/elogtool.c: Convert args into struct in flashrom helper

  vboot signatures for flashrom r/w helpers changed in the upstream
  commit bd2971326ee94fc5. Reflect the change here to allow vboot ref
  and coreboot to realign.

BUG=b:207808292,b:231152447
TEST=builds with vboot_ref uprev.
