Subject: [PATCH] systemd-boot: use mktemp from coreutils in installer

People running nixos-install in non-NixOS environments
occasionally run into the mktemp builtin not being loaded
into bash (yes, even NixOS' bash). Rather than try and
figure out why exactly that is happening, just use a known
good mktemp from coreutils.
