kernel-install: Try some more initrd variants in 90-loaderentry.install

On CentOS/Fedora, dracut is configured to write the initrd to
/boot/initramfs-$KERNEL_VERSION...img so let's check for that as well
if no initrds were supplied.

(cherry picked from commit b56920e36c5692c0dde701bfb48330653a9c62c9)
