binman: Add support for flashrom FMAP

Add an entry which can hold an FMAP region as used by flashrom, an
open-source flashing tool used on Linux x86 machines. This provides a
simplified non-hierarchical view of the entries in the image and has a
signature at the start to allow flashrom to find it in the image.
