Purge qdbusxml2cpp generated files

Following files were accidentaly added with 89b1f72 - "reorganized
bluetooth-qt and added declarative plugin". Should have been removed
with 3c761da - "cleaned up tree" but left unnoticed.

bluez-qt/obex/obexagent.cpp
bluez-qt/obex/obexagent.h
bluez-qt/obex/obexclient.cpp
bluez-qt/obex/obexclient.h
bluez-qt/obex/obexsession.cpp
bluez-qt/obex/obexsession.h
bluez-qt/obex/obextransfer.cpp
bluez-qt/obex/obextransfer.h

Consequently, the following files were added with f093ab9.

bluez-qt/obex/obexfiletransfer.h
bluez-qt/obex/obexobjectpush.cpp
