Add lzo support to mtd-utils

Add LZO support to mtd-utils to generate LZO compressed jffs2 images

Unlike the kernel version, the standard lzo userspace library is used
along with lzo1x_999_compress rather than the lzo1x_1_compress version
since better compression ratios can be obtained (at no significant cost
to decompression time).
