Do not enable the use_tablet flag in qemu, as this breaks the mouse.

-"""Makes changes to mounted Chromium OS image to allow it to run with VMs
-
-This script changes two files within the Chromium OS image to let the image
-work with VMs, particularly QEMU
-
-Currently this script does the following,
-1.) Modify the post install script to remove EFI fixup section; the VM's we
-support don't have EFI support anyway and this section of the script needs
-access to the actual device drives
-
-2.) For QEMU/KVM, we change the xorg.conf to remove mouse support and instead
-change it to complete tablet support. This is done to provide better mouse
-response in the VM since tablets work of absolute coordinates while the mouse
-works of relative. In a screen that doesn't support a mouse grab (e.g., VNC),
-relative coordinates can cause the mouse to be flaky
