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.

Attempt to fix bad bootsectors
...
Some (recent) ISO images have started having a zero byte as the first
byte of the MBR boot code embedded in the hard disk image.
When the original Lenovo ISO is booted, nobody has reported any issues,
however when a patched IMG file is created from that, it just hangs
- which does match with having bad bootcode data.
I was unable to reproduce the issue when running the images in qemu,
which is even more confusing.
Since every working image has the same first byte (a "CLI" instruction)
we attempt to repair things by simply changing it back to that byte.
