Revert "futility: Use flashrom for 'dump_fmap -x'"

It seems likely that this is causing the reported autoupdate failure,
although it will take a bit of time to understand the mechanism. For
now, a revert seems safest.

BUG=chromium:20939
BRANCH=none
TEST=none
This revert should be safe since it takes us back to the previous behavior.
I will work on repeating the problem and diagnosing it properly.

This reverts commit c1bbc75e3ba77019c62eda69db556109faeba607.
