[RFC PATCH 08/16] patman: Add a 'test' subcommand

[Simon Glass <sjg@chromium.org>]

At present we use --test to indicate that tests should be run. It is
better to use a subcommand for list, like binman. Change it and adjust
the existing code to fit under a 'send' subcommand, the default.

Give this subcommand the same default arguments as the others.
