Minor systemd-boot update

Systemd-boot has a minor change to loader.conf, basically they are adding ‘.conf’ to end of default config in line with entry file names. Have tested an updated iso and it seems to still boot via uefi. Have made change too abinstall but have not tested yet. Iso uploaded dated 2903 with changes. Old installs should still boot fine, just be aware that if you update via bootctl it may fail (something I need to check on my own system)
