Remove deprecated -no-kvm option 

The option has never been mentioned in our documentation, it's been
deprecated since years, it's marked with QEMU_ARCH_I386 (which does
not make sense anymore since KVM is available on other architectures,
too), it does not do anything by default in upstream QEMU (since TCG
is the default here anyway), and we're spending too much precious time
each year discussing whether it makes sense to keep this option as a
nice suger or not... let's finally put an end on this and remove it.
