Simple, clumsy script to test layout handling

Not for merge.

First parameter are flashrom options, second an optional layout file
(if not provided, `--ifd` will be used). e.g.

sh util/test_layout "-p dummy:emulate=MX25L6436,image=/tmp/dummy.rom -c MX25L6436E/MX25L6445E/MX25L6465E/MX25L6473E" util/test.layout
