So far, we relied on the module being copied over in the virtualenv, and the module itself would try to find config.status in parent directories of its own location. Unfortunately, this falls short when the source tree's build/ directory appears early in the sys.path. With this change, we don't copy the module to the virtualenv anymore, and try to find config.status in parent directories of the python executable, which, when running from the virtualenv, will be equivalent to the current behavior.
