Update build targets where possible

It seems that Lenovo has either changed the way they build their FL2
files, or has generated a bunch of broken update ISO images.

The two sysstems here still have a FL2 file with a EC firmware at offset
0x500000.

The remainder of the systems have updated BIOS ISO images available with
FL2 files that have nothing in them until offset 0x80000.  Older FL2 versions
have also had data at that offset but it previously looked like rubbish left
over from an FL1 UEFI capsule.
