[PATCH v2 20/38] binman: Add a bintool implementation for ifwitool

[Simon Glass]

Add a Bintool for this, which is used to build Intel IFWI images. It
supports the features needed by the tests as well as downloading a binary
from Google Drive. Although this is built in the U-Boot tree, it is not
currently included with u-boot-tools, so it may be useful to install a
binary on the system.
