run-tests: work around the Windows firewall popup for server processes

Windows doesn't have a `python3` executable, so cc0b332ab9fc attempted to work
around the issue by copying the current python to `python3.exe`.  That put it in
`_tmpbindir` because of failures in `test-run-tests.t` when using `_bindir`,
which looked like a process was trying to open it to write out a copy while it
was in use.  (Interestingly, I couldn't reproduce this running the test by
itself in a loop for a couple of hours, but it happens constantly when running
all tests.)  The problem with using `_tmpbindir` is that it is the randomly
generated path for the test run, and instead of Windows Firewall remembering the
executable signature or image hash when allowing the process to open a server
port, it apparently remembers the image path.  That means every run will trigger
a popup to allow it, which is bad for firing off a test run and walking away.

I tried to symlink to the python executable, but that currently requires admin
priviledges[1].  This will prompt the first time if the underlying python binary
has never opened a server port, but appears to avoid it on subsequent runs.

Requesting just the public heads works
