Replace --console=plain with -Dorg.gradle.console=plain

gradleSetupHook now includes `--console plain`: NixOS/nixpkgs@c12b2a0

Gradle errors when `--console` is passed twice: gradle/gradle#30913

This means that, before this commit, `buildGradleApplication` could not
run successfully with nixpkgs revisions which include the linked commit.

`-D` property flags are merged with each other, with properties set in a
file, and also with the `--console` flag, so after this commit, the
function can be used with nixpkgs both before and after the linked
commit, with the desired behavior: using a "plain" console.
