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.

# By default, use our own standalone_fuzz_target_runner.
# This runner does no fuzzing, but simply executes the inputs
# provided via parameters.
# Run e.g. "make all LIB_FUZZING_ENGINE=/path/to/libFuzzer.a"
# to link the fuzzer(s) against a real fuzzing engine.
#
# OSS-Fuzz will define its own value for LIB_FUZZING_ENGINE.
