setup: don't skip the search for global hg.exe if there is no local instance The point of trying not to blindly execute `hg` on Windows is that the local hg.exe would be given precedence, and if py3 isn't on PATH, it errors out with a modal dialog. But that's not a problem if there is no local executable that could be run. The problem that I recently ran into was I upgraded the repo format to use zstd. But doing a `make clean` deletes all of the supporting libraries, causing the next run to abort with a message about not understanding the `revlog-compression-zstd` requirement. By getting rid of the local executable in the previous commit when cleaning, we avoid leaving a broken executable around, and avoid the py3 PATH problem too. There is still a small hole in that `hg.exe` needs to be deleted before switching between py2/py3/PyOxidizer builds, because the zstd module won't load. But that seems like good hygiene anyway.
