kvm tools: Don't sort command-list.txt for help text

This patch removes the alphabetical sorting from util/generate-cmdlist.h so
that 'kvm run' command, for example, is displayed first:

  $ ./kvm

   usage: kvm [--version] [--help] COMMAND [ARGS]

   The most commonly used kvm commands are:
     run       Start the virtual machine
     pause     Pause/resume the virtual machine
     version   Print the version of the kernel tree kvm tools
     list      Print a list of running instances on the host.
     debug     Print debug information from a running instance
     balloon   Inflate or deflate the virtio balloon

   See 'kvm help COMMAND' for more information on a specific command.
