rendernode example: do not rely on build-time shader compilation

There is no public intrastructure for this. Relying on the internal qmake
rule in qtdeclarative is wrong as it is not meant for public consumption
and is not available in out of tree examples in the installed Qt anyway.

Instead, ship the bytecode for now.
