Export ZFS root pool before rebooting from the auto-installer

Check NixOS configurations / eval-hosts (pull_request) Successful in 10m19s

Details

disko's --mode ...,mount leaves the pool imported (needed for
nixos-install to write into /mnt), and the script rebooted straight
into the newly-installed system without exporting it. That pool is
still stamped with the live installer's own hostid, which never
matches the target host's declared networking.hostId, and since
boot.zfs.forceImportRoot is false (the recommended setting, not a bug),
the first real boot refuses to force-import an unexported pool from a
different hostid -- which is exactly the ZFS-import stall baremetal-gui
was hitting after install. Exporting all pools right before reboot (a
no-op for non-ZFS hosts) clears the in-use state so import succeeds
regardless of hostid.
