ns build android fails in CI environment without emulator

Issue Description

When building an Android app in a CI environment there is no need for emulator being installed, but it is required by CLI.

It might be related to #4265 I'm not sure if the author has requested the same thing or not so I created this issue.

Reproduction

Try to build an Android app using Github actions, or just inside a docker/podman container.

Relevant log output (if applicable)

✔ Your ANDROID_HOME environment variable is set and points to correct directory.
✔ Your adb from the Android SDK is correctly installed.
✔ A compatible Android SDK for compilation is found.
✔ Javac is installed and is configured properly.
✔ The Java Development Kit (JDK) is installed and is configured properly.
✔ Local builds for iOS can be executed only on a macOS system. To build for iOS on a different operating system, you can use the NativeScript cloud infrastructure.
✖ WARNING: The Android SDK is not installed or is not configured properly. 
 You will not be able to run your apps in the native emulator. To be able to run apps
in the native Android emulator, verify that you have installed the latest Android SDK 
and its dependencies as described in http://developer.android.com/sdk/index.html#Requirements

Comece por packages/doctor/src/android-tools-info.ts na verificação referenciada e, em seguida, reproduza o build no GitHub Actions ou em um contêiner Docker/Podman sem um emulador. Rastreie por que o requisito do emulador afeta os builds e verifique se um build Android é concluído com sucesso nesse ambiente sem exigir a instalação de um emulador.
