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).
