pipeline: raspberrypi: Free buffers in the RPiCamera destructor and re-configure

Currently, all framebuffer allocations get freed and cleared on a stop in
PipelineHandlerRPi::stopDevice(). If PipelineHandlerRPi::start() is then called
without an intermediate PipelineHandlerRPi::configure(), it will re-allocate and
prepare all the buffers again, which is unnecessary.

Fix this by not freeing the buffer in PipelineHandlerRPi::stopDevice(), but
insted doing it in PipelineHandlerRPi::configure(), as the buffers might have
to be resized.

Add a flag to indicate that buffer allocations need to be done on the next
call to PipelineHandlerRPi::start().
