[PATCH v2 21/24] binman: Add support for building a binmanu PyPi package

[Simon Glass]

Create the necessary files to build this new package.

It is not actually clear whether this is useful, since buildman has no
purpose outside U-Boot.

Move the main program into a function so that it can easily be called by
the PyPi-created script.
