Adding SIGWINCH to list of signals for "unix".

This is specifically to support running Apache 2.2 under consul-template.
Apache does a graceful stop on SIGWINCH (http://httpd.apache.org/docs/2.2/stopping.html#gracefulstop)

I checked that this signal is supported on Linux (debian in my case) and OSX.
