[Qemu-devel] [qemu-kvm RHEL7 PATCH] Add support statement to -help output

[Eduardo Habkost <ehabkost@redhat.com>]

Bugzilla: 972773
Brew scratch build: http://brewweb.devel.redhat.com/brew/taskinfo?taskID=6676272

Add support statement to -help output, reporting direct qemu-kvm usage
as unsupported by Red Hat, and advising users to use libvirt instead.
