androidenv: fix autoupdate and custom XMLs (#411999)

# How to update

1. `./fetchrepo.sh`

2. `./mkrepo.sh`

3. Check the `repo.json` diff for new stable versions of `tools`, `platform-tools`, `build-tools`, `emulator` and/or `ndk`

4. Update the relevant argument defaults in `compose-android-packages.nix`

`nix-shell maintainers/scripts/update.nix  --argstr package androidenv.test-suite --argstr commit true`

# How to run tests

You may need to make yourself familiar with [package tests](../../../README.md#package-tests), and [Writing larger package tests](../../../README.md#writing-larger-package-tests), then run tests locally with:

```shell

$ export NIXPKGS_ALLOW_UNFREE=1

$ cd path/to/nixpkgs

$ nix-build -A androidenv.test-suite.tests

$ nix-build -A androidenv.test-suite

```

    # Reads the repo JSON. If repoXmls is provided, will build a repo JSON into the Nix store.

    if repoXmls != null then

      let

        # Uses mkrepo.rb to create a repo spec.

        # Uses update.rb to create a repo spec.

        mkRepoJson =

          {
