sleep-script: Prevent bluetoothctl from timing out

If bluetooth is disabled in the BIOS, the bluetoothd process won't be
running. bluetoothctl waits for that process to launch, which means it
timeouts indefinitly, breaking suspend entirely.

By checking if bluetoothd is running before calling bluetoothctl suspend
works fine even if bluetooth is disabled in the BIOS.
