Subject: [PATCH] qemu: Drop QEMU_CAPS_ENABLE_KVM
It was already available in 1.5.0.
Moreover, we're not even formatting it on the QEMU command
line, ever: we just use it as part of some logic that decides
whether KVM support should be advertised, and as it turns out
that logic is actually buggy and dropping this capability
fixes it.
