Hello build bot (Jenkins), Jack Rosenthal, Nikolai Artemiev,

I'd like you to reexamine a change. Please visit

https://review.coreboot.org/c/coreboot/+/59714

to look at the new patch set (#7).

Change subject: util/cbfstool: Port elogtool to libflashrom

util/cbfstool: Port elogtool to libflashrom

This also uncouples cbfstool from being overly Chromium
specific. However the main objective is to not subprocess
flashrom any more and instead use the programmatic API.

BUG=b:207808292
TEST=built and ran `elogtool list`.
