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.

debuginstall extension support
  $ hg debuginstall --config extensions.fsmonitor= --config fsmonitor.watchman_exe=false | grep atchman
  fsmonitor checking for watchman binary... (false)
   watchman binary missing or broken: warning: Watchman unavailable: watchman exited with code 1
Verify the json works too:
  $ hg debuginstall --config extensions.fsmonitor= --config fsmonitor.watchman_exe=false -Tjson | grep atchman
    "fsmonitor-watchman": "false",
    "fsmonitor-watchman-error": "warning: Watchman unavailable: watchman exited with code 1",

Verify that Mercurial is installable with pip. Note that this MUST be
the last test in this file, because we do some nasty things to the
shell environment in order to make the virtualenv work reliably.

On Python 3, we use the venv module, which is part of the standard library.
But some Linux distros strip out this module's functionality involving pip,
so we have to look for the ensurepip module, which these distros strip out
completely.
On Python 2, we use the 3rd party virtualenv module, if available.

  $ cd $TESTTMP
  $ unset PYTHONPATH

#if py3 ensurepip
  $ "$PYTHON" -m venv installenv >> pip.log

Hack: Debian does something a bit different in ensurepip.bootstrap. This makes
it so that pip thinks the 'wheel' wheel is installed so it can build wheels;
when it goes to try, however, it shells out to run `python3 -u <setup.py>`,
that *doesn't* get the 'wheel' wheel, and it fails with an invalid command
'bdist_wheel'. To fix this, we just delete the wheel from where Debian put it in
our virtual env. Then pip doesn't think it's installed and doesn't try to build.
  $ rm installenv/share/python-wheels/wheel-*.whl >/dev/null 2>&1 || true

Note: we use this weird path to run pip and hg to avoid platform differences,
since it's bin on most platforms but Scripts on Windows.
