rpi-base.inc: Add w1-gpio-pi5.dtbo

Add w1-gpio-pi5.dtbo to RPI_KERNEL_DEVICETREE_OVERLAYS to resolve
the following issue noticed in vclog --msg on Raspberry Pi 5 when
ENABLE_W1 is set to 1:

dtdebug: mapped overlay 'w1-gpio' to 'w1-gpio-pi5'
dtdebug: Failed to open overlay file 'overlays/w1-gpio-pi5.dtbo'
