kvm: require KVM_CAP_SIGNAL_MSI
This was introduced in KVM in Linux 3.5, we can require it unconditionally in kvm_irqchip_send_msi(). However, not all architectures have to implement it so check it only in x86, the only architecture that ever had MSI injection but not KVM_CAP_SIGNAL_MSI. ARM uses it to detect the presence of the ITS emulation in the kernel, introduced in Linux 4.8. Assume that it's there and possibly fail when realizing the arm-its-kvm device.
