Previously, `pkgs.libreoffice` had a total closure-size of 2.4GB where
`pkgs.openjdk` was a significant part:
$ nix path-info ./result -Sh
/nix/store/7xyfklmiz2azcnrfa8n9cz12dyyqc85r-libreoffice-7.1.7.2 2.4G
$ nix path-info ./result -shr | grep openjdk
/nix/store/qcn7ihaak9g8ayyj4995ila2z0pkm37i-openjdk-17.0.1+12 643.6M
However we need exactly two components:
* a `javac` from `pkgs.openjdk`
* a minimal runtime (i.e. a JRE) for `libofficebean.so` where
`libjawt.so` is also available.
I moved `jdk` to the `nativeBuildInputs` to ensure that `javac` is still
available in the build-environment and created a minimal JRE that seems
sufficient.
Now, the total closure-size is reduced by ~29.1% (basically the 600M
from `pkgs.openjdk`):
$ nix path-info ./result -Sh
/nix/store/zv34xijv64k7sz7rv50g3v6y59qg7p8k-libreoffice-7.1.7.2 1.7G

LibreOffice
To generate src-$VARIANT/download.nix, i.e. list of additional sources that
the libreoffice build process needs to download:
nix-shell gen-shell.nix --argstr variant VARIANT --run generate
Where VARIANT is either still or fresh.
