accel/kvm: Adjust the note about the minimum required kernel version

Since commit 126e7f78036 ("kvm: require KVM_CAP_IOEVENTFD and
KVM_CAP_IOEVENTFD_ANY_LENGTH") we require at least kernel 4.5 to
be able to use KVM. Adjust the upgrade_note accordingly.
While we're at it, remove the text about kvm-kmod and the
SourceForge URL since this is not actively maintained anymore.
