es-menu: wire up AUTO FRAME DELAY and ship wg-quick for WIREGUARD VPN

Two ES menu items that wrote settings nothing consumed / called a missing
binary, found in the menu audit:

- AUTO FRAME DELAY (Latency menu) persisted `<config>.video_frame_delay_auto`
  to system.cfg, but setsettings.sh never translated it into retroarch.cfg,
  so the toggle did nothing. Add set_frame_delay(): ON/OFF -> RetroArch
  `video_frame_delay_auto = true/false`, AUTO leaves the cfg default.

- WIREGUARD VPN toggle runs `wg-quick up/down`, but the wireguard-tools
  package only installed `wg`, so every toggle silently failed. wg-quick is
  the upstream bash helper (src/wg-quick/linux.bash); install it. Runtime
  deps (bash, ip, wg, iptables) are all present.
