sandybridge: Make inclusion of me.bin optional

Current build configuration always wants to include an Intel Management
Engine firmware (me.bin) on Sandy Bridge systems. However, we can have
a working coreboot without it, as long as the factory delivered ME
firmware is kept untouched in the flash ROM. So let the user decide if
a ME firmware will be included in the build.

help
The Intel processor in the selected system requires a special firmware
for an integrated controller called Management Engine (ME). The ME
firmware might be provided in coreboot's 3rdparty repository. If
not and if you don't have the firmware elsewhere, you can still
build coreboot without it. In this case however, you'll have to make
sure that you don't overwrite your ME firmware on your flash ROM.
