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.
