Silvan Mosberger c70a466d21 nixos/systemd: Allow creation of unit directories
This patch allows creation of files like
/etc/systemd/system/user-.slice.d/limits.conf with

    systemd.units."user-.slice.d/limits.conf" = {
      text = ''
        [Slice]
        CPUAccounting=yes
        CPUQuota=50%
      '';
    };

which previously threw an error

Also renames the systemd-unit-path test to sytsemd-misc, and extends it to
test that `systemd.units` can handle directories. In this case we make
sure that resource limits specified in user slices apply.
