prl-tools: 12.2.1-41615 -> 17.1.4-51567

Browse source 
Install Parallel Tools updated for version 17 of Parallels for macOS. This
fixes clipboard sharing, so that copy and paste works between the host
macOS and the guest NixOS VM. Support for guests on M1 Apple Silicon-based
Macs (aarch64-linux) is also added.
