net/yggdrasil: Update to 0.5.7

ChangeLog: https://github.com/yggdrasil-network/yggdrasil-go/releases/tag/v0.5.7

Added

 * WebSocket support for peerings, by using the new ws:// scheme in Listen and
   Peers
 	* Additionally, the wss:// scheme can be used to connect to a WebSocket peer
	behind a HTTPS reverse proxy

Changed

 * On Linux, the TUN adapter now uses vectorised reads/writes where possible,
   which should reduce the amount of CPU time spent on syscalls and potentially
   improve throughput
 * Link error handling has been improved and various link error messages have
   been rewritten to be clearer
 * Upgrade dependencies

Fixed

 * Multiple multicast connections to the same remote machine should now work
   correctly
	* You may get two connections in some cases, one inbound and one
	  outbound, this is known and will not cause problems
 * Running as a Windows service should be more reliable with service startup and
   shutdown bugs fixed
