hghave: update the check for virtualenv

This started as `hghave --test-features` failing on Windows in `test-hghave.t`.
IDK how this worked, as neither my Linux nor Windows machines have the old
attribute with virtualenv 20.2.2, even on py2.  I think this was noticed
recently because 357d8415aa27 mentioned an AttributeError, and mitigated by
making this py2 only.  But as mentioned, this is also a problem on py2 (where
the failure was observed).

When I got this working by removing the attribute reference, the command in the
test failed because the `--no-site-package` argument was removed some time ago.
Therefore, this backs out 357d8415aa27 and references a known good attribute
(which was done to suppress the warning about an unused import) that also
ensures the command does not need the argument.  Since there appears to be
(minor) broken stuff on py3, manually apply the `no-py3` guard that was backed
out of the check itself.

====================================
Testing head checking code: Case D-7
====================================

Mercurial checks for the introduction of new heads on push. Evolution comes
into play to detect if existing branches on the server are being replaced by
some of the new one we push.

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

Category D: remote head is "obs-affected" locally, but result is not part of the push
TestCase 7: single changesets, superseeded multiple time then pruned (on a new changeset unpushed) changeset

This is a partial push variation of B6

.. old-state:
..
.. * 1 changeset branch

.. new-state:

.. * the new version is then pruned.
