binman: Allow verbosity control when running tests

At present the -v flag is ignored with tests, so that (for example) -v2
does not have any effect. Update binman to pass this flag through to tests
so that they work just like running binman normally, except in a few
special cases where we are actually testing behaviour with different
levels of verbosity.
