Do various small fixup/cleanups and extend test script to boot kernel image from UBI volume. This test verifies that U-Boot UBI implementation is working and U-Boot can read volume with bootable kernel code correctly. And therefore CI prevents UBI breakage.
Note that U-Boot UBIFS code on ARM is currently somehow broken and trying to mount UBIFS from UBI volume fails :-( I have already tried to debug this issue but I have no idea why it is failing. Function check_lpt_crc in unpack_ltab is failing. Volume is for sure correct and valid because Linux kernel can successfully mount it. And to make it more suspicious, U-Boot UBIFS is working fine on big endian powerpc platform. So UBIFS issue is probably endian or arch specific. (This is UBIFS related, not UBI related.)
