File virtman-prevent-double-click-starting-vm-twice.patch of Package virt-manager.2133

Reference: bnc#874594
When the 'Power on virtual machine' button is double clicked,
virt-manager issues two start commands to start the VM which
results in a failure. There is code elsewhere to desensitize the
button but this patch does it earlier.
