[PATCH v2 04/28] binman: Give a sensible error if no command is given

[Simon Glass]

At present if 'binman' is typed on the command line, a strange error about
a missing argument is displayed. Fix this.

These does not seem to be standard way to add the 'required' argument in
all recent Python versions, so set it manually.
