sys-apps/systemd: add USE=kernel-install,ukify

AFAIK there is no reason why we could not use systemd's
kernel-install with other bootloaders then systemd-boot.
The systemd version of kernel-install has the advantage
that its behaviour can be customized with plugins. This
is the first step to make it possible to use Gentoo's
dist-kernels with initrd generators other then Dracut.
