run-tests: no longer pass a TestRunner into Test.__init__

We no longer access any attributes on TestRunner besides options, so we
stop passing a TestRunner to Test.__init__ and now pass the options
data structure instead.

Subsequent patches will move accessed options attributes into named
arguments.
