packages: use an Android phone's NFC as a smart card reader

Browse source 
Register vsmartcard's vpcd with pcscd as "Virtual PCD", so the
Remote Smart Card Reader app on a phone can serve the ID card over
NFC as a PC/SC reader. Over USB the link is an adb port reverse
(adb reverse tcp:35963 tcp:35963), hence android-tools.
