kernel-build.eclass: sign the kernel image earlier in src_install
By signing it in src_install instead of pkg_postinst the signed version is
included in any generated binpkg. This is useful for enabling secureboot
on machines that do not have the secureboot private key available.
This change makes it possible to distribute a signed kernel image in
sys-kernel/gentoo-kernel-bin.
Note, UKIs are always generated locally, so if UKIs are used these will still
have to be signed in pkg_postinst and therefore the private key is still
required on all systems with USE=secureboot and uefi=yes in dracut.conf.
