Try both IPv4/6 when connecting to XBMC

Apparently the Gotham nightly (xbmc-package-xbmc-gotham-nightly) only listens on IPv6 if the system has IPv6 configured:
`tcp6       0      0 ::1:9090                :::*                    LISTEN      4514/xbmc.bin`

Setting the address to `localhost` and using `socket.create_connection` the connection is attempted on both address families.
Also, specifying `SOCK_STREAM` is not necessary, as it's the default on Python 2.7 (*bian default) to 3.4.
