Fix bytesperline calculation for libcamera0.2

[KapJI]

For libcamera0.2 configuration.stride is already set to some incorrect value and configurations->validate() doesn't update it if it's not 0.

For libcamera0.1 it was set to 0. So set it to 0 manually to make sure configurations->validate() computes the correct value.

Before:

device/buffer_list.c: CAMERA:capture: Using: 1920x1080/YUYV, buffers=3, bytesperline=3840, sizeimage=0.0MiB
device/buffer_list.c: CAMERA:capture:1: Using: 2304x1296/BG10, buffers=3, bytesperline=5760, sizeimage=0.0MiB
ERROR V4L2 v4l2_videodevice.cpp:1697 /dev/video13[26:out]: Failed to queue buffer 0: Invalid argument
ERROR RPISTREAM rpi_stream.cpp:276 Failed to queue buffer for ISP Input

After:

device/buffer_list.c: CAMERA:capture: Using: 1920x1080/YUYV, buffers=3, bytesperline=3840, sizeimage=0.0MiB
device/buffer_list.c: CAMERA:capture:1: Using: 2304x1296/BG10, buffers=3, bytesperline=2880, sizeimage=0.0MiB

Tested both with libcamera0.1 and libcamera0.2 on raspberry pi 4. Errors are gone and streaming works fine with libcamera0.2 finally.

Thanks to @tom-ard for help with debugging.

I just came to say thanks @KapJI ! I spent the last 4 hours troubleshooting my camera then found this. I made the change and instantly I'm up and running!. @ayufan please pull this ASAP. I found my way here from crowsnest and it was not an easy journey lol.

@ayufan Can you pls. "Merge" this again? Seems like the files to download Expired - Or even better make a new "Release"

Where do you set configuration.stride = 0?
