gitea: fix passthru.data-compressed

Fixes two bugs:
- pass a forgotten `{}` to `compressDrv`.
- remove incorrect usage of `lndir` in `compressDrv`. I added a brief
  comment on why, see [this comment][1] for more details.

Tested with:

```
$ nix build .#legacyPackages.x86_64-linux.gitea.passthru.data-compressed
$ ls -lh result/public/assets/licenses.txt*
