The previous variant used IFD to generate the `JAVA_HOME` variable and relied on internal hooks of the `java` package, this failed for a user cross compiling their configuration.
This PR changes that and uses the `home` attribute, as documented in the very last sentence of the https://nixos.org/manual/nixpkgs/stable/#sec-language-java chapter.
