[JFFS2] Add a "favourlzo" compression mode
Add a "favourlzo" compression mode to jffs2 which tries to optimise by size but gives lzo an advantage when comparing sizes. This means the faster lzo algorithm can be preferred when there isn't much difference in compressed size (the exact threshold can be changed).
