board/raspberrypi: Support boot.scr for U-Boot

Browse Source 
If using U-Boot as "kernel" for the raspberrypi bootloader, include
boot.scr in the boot partition if it exists.

To use this, use BR2_PACKAGE_RPI_FIRMWARE_CONFIG_FILE to set a config
file that uses U-Boot, and enable building a boot script in the U-Boot
host tool settings.
