util/ifdtool: Add option to create FMAP template

On systems that do not provide their own *.fmd (Flashmap) file, we
fall back to a default flashmap file. That file however does not contain
the blobs (ME, GBE ...), that are usually placed below the BIOS Flashmap.
It can therefore easily happen that the placement of the blobs collides
with the placement of the BIOS region (e.g. if CBFS_SIZE is big enough).
The fmaptool can't catch that, since it does not know of the blobs
placement.

This patch basically maps the regions described in the IFD (Intel
Firmware Descriptor) to the default Flashmap.

Test: Build and see that build/fmap.fmd contains all blobs now (on intel
systems that are supported by the ifdtool)
