pipeline: raspberrypi: Update naming convention for tuning files

Browse source 
Append "_mono" to the sensor name when generating the tuning filename for
monochrome sensor variants. So the new naming convention is as follows:

<sensor_name>.json - Standard colour sensor variant
<sensor_name>_mono.json - Monochrome sensor variant

Rename the existing imx296.json file to imx296_mono.json as this tuning file
is based on the monochrome variant of the IMX296.
