ssl: resolve symlink before checking for Apple python executable (issue4588)

test-https.t was broken at 07fafcd4bc74 if /usr/bin/pythonX.Y is used on
Mac OS X.

If python executable is not named as "python", run-tests.py creates a symlink
and hghave uses it. On the other hand, the installed hg executable knows the
real path to the system Python. Therefore, there was an inconsistency that
hghave said it was not an Apple python but hg knew it was.

This test is dedicated to test the bundle2 container format

It test multiple existing parts to test different feature of the container. You
probably do not need to touch this test unless you change the binary encoding
of the bundle2 format itself.

Create an extension to test bundle2 API
