kernel-install: describe usage as installkernel

Browse source 
For us, this is a compatibility mode, but most likely it is there to stay: the
kernel Makefile's install target expects to be able to call /bin/installkernel.
We want people who build their own kernels to use this, so that they use
kernel-install and get support for all the functionality provided by it,
including building of UKIs and other new features. So let's actually advertise
that this exists and works.
