Add TLSv1 support for URLLIB2

This fix will allow MunkiReport-PHP when running on either OS X 10.10
Server or a newer version of Apache to use TLSv1 as the default
protocol when submitting data as Python by default uses SSL.  Thanks to
https://gist.github.com/flandr/74be22d1c3d7c1dfefdd for the fix.
