The aapt package form Debian might not be recent enough to install the
packages from Android CTS.
Resulting in an error like:
```
03:12:09.302: Module(s) with run failure(s):
03:12:09.302: x86_64 CtsGraphicsTestCases: com.android.tradefed.targetprep.TargetSetupError[AAPT_PARSER_FAILED|520050|DEPENDENCY_ISSUE]: AaptParser failed for file CtsGraphicsTestCases.apk. The APK won't be installed
```
So get aapt from the build-tools matching the ANDROID_SDK_VERSION
corresponding to the Android version and CTS version used in the tests,
to ensure compatibility.
This effectively reverts the changes from commit b3c07fe722
(ci/android: Use aapt from Debian packages, 2025-04-21), but moving the
code around a bit.
The build-tools are not taken as LAVA overlay because LAVA is not able
to handle zip files, and the file in not big enough to be worth any
repacking effort.
