Matthias Treydte a30de3b849 nixos/systemd-boot: fix systemd-boot-builder dowgrade to fail
Since, 4ddc78818e systemd-boot-builder
is broken in two ways:

  * if no systemd-boot is currently installed *and* the NIXOS_INSTALL_BOOTLOADER
    env variable is not set, it will try to run "bootctl update", which will fail
  * if the currently installed systemd-boot version is newer than the version
    we're about to install, it will also try to run "bootctl update", which will fail

This patch changes the behaviour,

  * for the first case to still fail, but not even bother to try running
    "bootctl update" and instead erroring out with an exception
  * for the second case to leave the newer version in place, restoring
    the pre - 4ddc78818e behaviour

To do the proper version check a new "should_update" helper function was introduced,
mimicing the compare_product C function from bootctl. If the following systemd
issue gets resolved, we would have a nice way to get rid of this function:

This change allows to again switch to a different NixOS configuration which contains
an older systemd-boot.
