Subject: [PATCH] nixos/systemd-initrd: create the /tmp mount point in the
 initrd

systemd now requires the /tmp mount point in the initrd cpio archive
since https://github.com/systemd/systemd/pull/25723

setting `"/tmp/.keep".text` will create the directory.

this fixes a boot failure:
```
(sd-gens): Failed to overmount /tmp/: No such file or directory
```
