configs/colibri_vf.h: drop sdboot in favour of distro_bootcmd

The distro bootscript uses kernel_image to get the file name of
the kernel, so change that variable name.
UBI boot has precedence in the default boot command. If one wants
to boot from SD with a working NAND installation stop in U-Boot
and enter:

setenv fdtfile ${soc}-colibri-${fdt_board}.dtb && run distro_bootcmd
