blobutil: support extracting ME from full ROMs
In cases where the vendor update file contains a full
ROM image encompassing IFD+GbE+ME+BIOS, blobutil was
saving the *entire* ROM containing those, as me.bin.
For example, if it's an 8MB ROM, blobutil would create
a me.bin file that is actually the whole ROM containing:
* Vendor IFD region
* Vendor GbE(if it has one)
* Vendor ME region
* Vendor BIOS region
This fix tries with -M and -O first. In this combination,
me_cleaner shall extract me.bin (neutered) and save it.
If that fails, then the normal method with just -O is
tried, which by this logic would always be a lone ME
image if it succeeds.
I tested downloading ME images on existing boards with
this, and it didn't break them, and this fixes the bug.
This is done for HP 8200 SFF which Riku_V is adding to
lbmk. I'm on IRC with Riku_V as I write this commit
message! Super hot hotfix patch.
