sslutil: issue warning when unable to load certificates on OS X

Previously, failure to load system certificates on OS X would lead
to a certificate verify failure and that's it. We now print a warning
message with a URL that will contain information on how to configure
certificates on OS X.

As the inline comment states, there is room to improve here. I think
we could try harder to detect Homebrew and MacPorts installed
certificate files, for example. It's worth noting that Homebrew's
openssl package uses `security find-certificate -a -p` during package
installation to export the system keychain root CAs to
etc/openssl/cert.pem. This is something we could consider adding
to setup.py. We could also encourage packagers to do this. For now,
I'd just like to get this warning (which matches Windows behavior)
landed. We should have time to improve things before release.
