hghave: change ssl check to just check ssl module

Previously, the "ssl" check effectively looked for PyOpenSSL
or Python 2.7.9. After this patch, we simply look for just the
"ssl" module.

After d962e955da08, there have been no references to PyOpenSSL in
the tree (the previous usage of PyOpenSSL was to implement ssl
support on old, no longer supported Python versions that didn't
have an ssl module (e.g. Python 2.4). So, the check for PyOpenSSL
served no purpose.

Pythons we support ship with the ssl module. Although it may not be
available in all installations. So, we still need the check for
whether the ssl module imports, hence the hghave check.

The main side-effect of this change is that we now run test-https.t
(the only test requiring the "ssl" hghave feature) on Python <2.7.9
when PyOpenSSL is not installed (which is probably most installations)
and the ssl module is available. Before, we wouldn't run this test
on these older Python versions.

I confirmed that test-https.t passes with Python 2.6.9 and 2.7.8 on
OS X 10.11.
