binman: Specify the toolpath when running test coverage

At present binman's test coverage runs without a toolpath set. This means
that the system tools will be used. That may not be correct if they are
out of date or missing and this can result in a reduction in test coverage
below 100%.

Provide the toolpath to binman in this case.
