rsync: 3.1.2 -> 3.1.3

The CVE patches weren't previously applied because they depend on the
enableCopyDevicesPatch parameter. The naming of the patches attribute in
base.nix was misleading.

The new rsync release now really fixes:

* CVE-2017-15994
* CVE-2017-16548
* CVE-2017-17433
* CVE-2017-17434
