Fix Chromium autofill timing bug + RDP anti-idle to prevent lock screen

- universal-runtime: set _state[profile_dir] AFTER _start_process so
  _stop_current does not delete the freshly-created profile before
  Chromium reads it. Without this, Login Data was being wiped.
- rdp-proxy: add xdotool dependency and background anti_idle_loop that
  sends Shift to the xfreerdp window every 30s, forwarded over RDP to
  reset the remote idle timer and keep the lock screen from kicking in.
