Fix system X cursor Chromium 151*

I posted that Chromium 151.* was no longer recognizing the system cursor.

Forum member NorthernSoul found a solution, adding this line in /etc/gtk-3.0/settings.ini:

gtk-cursor-theme-name = default

Good, but it does pose a problem when update Easy from an earlier version, as that settings.ini file may have user-customizations. That means, although I have fixed it in easy.sfs, the bottom layer of overlayfs, the user-customized settings.ini will be on the top read-write layer of overlayfs.

Therefore, in the initrd, I am putting in some code to check if there is a settings.ini on the read-write layer, and append that extra line onto it.
