FP3: Enable ZRAM

Description

Enable ZRAM.

ZRAM is a Linux kernel module for creating a compressed block device in RAM.

Data stored in a zRAM partition is compressed, so more data can be stored in RAM. And although a small percentage of CPU time is used for this compression, the performance trade off is often worth it. Reference

It was recently discovered by a forum member that FP3's kernel has the required support to enable this feature. It just had to be configured and enabled in device configuration side.
