automation: set PATH when building on Windows

Sometime in the 6.2 release cycle the Windows building automation
broke. Building the wheel and even PyOxidizer based installers now fails
with:

```
Exception: PowerShell execution failed:   error: subprocess-exited-with-error
Getting requirements to build wheel did not run successfully.
exit code: 1
[1 lines of output]
Unable to find a working hg binary to extract the version from the repository tags
[end of output]
note: This error originates from a subprocess, and is likely not a problem with pip.
```

I have a hunch this is a regression from upgrading pip in 1c00777702da,
but I haven't verified this. It may not be, as PyOxidizer has its own
bundled Python/pip. So maybe it is something in `setup.py`.

=========================================
Testing single head enforcement: Case A-4
=========================================

A repository is set to only accept a single head per name (typically named
branch). However, obsolete changesets can make this enforcement more
complicated, because they can be kept visible by other changeset on other
branch.

This case is part of a series of tests checking this behavior.

Category A: Involving obsolescence
TestCase 4: Partial rewrite of a branch to deinterleave it

.. old-state:
..
.. * 2 changesets on branch default
.. * 2 changesets on branch Z interleaved with the other one
..
.. new-state:
..
.. * 2 changesets on branch Z at the same location
.. * 1 changeset on default untouched (the lower one)
.. * 1 changeset on default moved on the other one
..
.. expected-result:
..
.. * only one head detected

Actual testing
--------------

(force push to make sure we get the changeset on the remote)

  $ hg push -r 'desc("C1")' --force
  pushing to $TESTTMP/A4/server
  searching for changes

  adding manifests
  adding file changes
  added 1 changesets with 1 changes to 1 files (+1 heads)
  1 new obsolescence markers
  obsoleted 1 changesets
