kirkwood: cleanup image build code

Drop NAND_BLOCKSIZE, UBI_OPTS and UBIFS_OPTS. They are either used by
not supported filesystems or by the legacy image build code.

Add common used options/images to the default build code and override
the options where necessary.

Don't export the kernel image, it isn't required by any board.

While at it, change the file extension for the sysupgrade images to bin.
