sys-kernel/installkernel-systemd-boot: allow systemd(-utils)[kernel-install]

We can use kernel-install with other boot loaders if we provide suitable
plugins in /usr/lib/kernel/install. This is part of the effort to
allow users to use other initrd generators for the dist-kernels.

And make kernel-install verbose, otherwise it doesn't output anything at all
during dist-kernel install.
