    aries-common: use KitKat zRAM setting

    CM's compcache has been removed, so we need to migrate to KitKat's
    mechanism. The value is set to 64 MB for now, which is approximately
    equal to the old 18% setting.

    aries-common: increase zRAM to 128 MB

    This gets compressed to ~40 MB on RAM and may provide benefits
    to multitasking.
