I was using ansible_os_family to get settings for Debian-family

I don't have any Debian hosts here, but anyways, it's better this
way so I can be more flexible in the future.

roles/nginx: Enable OCSP stapling
...
Reduces round trip time for clients. Note: I am using a certificate
chain in the `ssl_certificate' directive, so as I understand it, I
don't need to use an explicit trusted intermediate + root CA cert
with the `ssl_trusted_certificate' option. See the nginx docs for
more[0]. Addresses GitHub Issue #5 .
Seems to be working, test with:
$ openssl s_client -connect mjanja.ch:443 -servername mjanja.ch -tls1 -tlsextdebug -status
Look for "OCSP Response" with "Cert Status: good".

Use "public" with "max-age" instead of Expires, as "max-age" is always
