www/ruby-patron: update to 0.13.0

### 0.13.0

* Permit timeouts to be set as a Float of seconds and use \ 
`CURLOPT_(CONNECT)TIMEOUT_MS` instead of `CURLOPT_(CONNECT)TIMEOUT` so that
  sub-second timeouts can be configured, which is useful for performant services \ 
using accelerated DNS resolution.
* Remove the restriction that `Session#timeout` should be non-zero - a timeout \ 
set to 0 means "no timeout" in libCURL
