improve pdu generation in SmsListenerTest

Browse Source 
one Android 2.3.3 device was throwing NPEs while parsing the precompiled
pdu test vectors so I modified SmsListenerTest to generate them on the fly
using Android's own PDU related classes. All tests now pass on 2.3.3,
4.2.2, 4.4.4, 5.1.

Closes #3048
