IMHO, I think it's best to implement the ME unlock sequence in a separate utility, placed inside the util/ subfolder. In case the fwupd people want to use this tool as a library, it should be very easy to implement it as a tiny library with a slim front-end (for the standalone utility).

Given that fwupd most likely needs to be adapted to handle the ME unlock sequence, going with a separate utility shouldn't be much of an issue.
