Termix: add guacd build and systemd integration

Install and build Apache Guacamole Server (guacd) and integrate it with Termix.

- Added required native dependencies to install/termix-install.sh and build steps to download, compile and install guacd, recording its tag in ~/.guacd.
- Created /etc/guacamole/guacd.conf and a systemd unit for guacd; enabled and started guacd alongside termix, and made termix.service depend on guacd.
- Extended ct/termix.sh update flow to detect guacd GitHub tags, stop guacd, rebuild/install the specified release, add default config/unit files if missing, and enable/start the service.
- Minor messaging tweaks: use "Termix" in stop/start logs.

This ensures guacd is available and managed automatically when installing or updating Termix.
