Subject: binman: Give a sensible error if no command is given
X-Git-Tag: v2021.10~451^2~24

binman: Give a sensible error if no command is given

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.
