Drop fixup_image_for_qemu.py; ChromeOS works fine in qemu/kvm without an xorg.conf

Browse Source 
fixup_image_for_qemu.py exists only to add an xorg.conf; however, Xorg's
autodetection has handled qemu/kvm just fine for quite a while now, with
or without -vga std.  Drop the script and the call to it from
image_to_vm.sh.

BUG=None
TEST=Build an image, confirm that it still works fine in kvm and
     autodetects an appropriate resolution.
