[Sony Xperia Tablet Z] Make /system/ writable

Next, I needed to make /system writable on the Tablet Z.

The instructions below worked for me:

I used almost the same commands except busybox was not available on my tablet.

Instead, I used ps and kill command to remove the /sbin/ric process.

shell@android:/sdcard/hydrive $ ps | grep ric

NOTE: This is a temporal solution, meaning you will need to do it again after your system reboots.
