python-tornado: fix runtime dependencies

According to setup.py tornado requires backports.ssl_match_hostname
for Python < 3.2 and certifi for Python < 3.4.

Actually both requirements are optional and tornado alone can work
without them, but Python packages like python-circus check requirements
at runtime and though they don't use this funtionality, they insist on
having these packages installed.

An upstream patch fixes backports.ssl_match_hostname dependency and
selecting python-certifi for Python 2 fixes certifi dependency till
this is fixed upstream.

+Subject: [PATCH] Don't require backports.ssl_match_hostname on Python 2.7.9
+ and newer
+
+As Python 3.2 support was dropped one can check 2.7.x dependency only.
+
+Tornado running on Python 2.7.9+ doesn't need this backported package,
+but some Python packages like circus check package dependencies at
+runtime and insist on having backports.ssl_match_hostname installed,
+though they don't even use this particular feature.
+
+So checking for exact version makes life of package maintainer easier
+especially on embedded Linux distributions like Buildroot.
