universal7885: rootdir: Tune zram performance

Browse source 
- Switch to LZ4 for better overall performance
- Set max_comp_streams to num of cores since upstream also moves this to
percpu.
- Set page-cluster to 0 as the incremental cost of reading 1 page at a
time is negligible for zram

[roynatech2544: Adjust swappiness too]

Bug: 38249616
Test: boot and run zram-perf showing better performance
