This commit fixes 2 main problems:
- Android Studio comes with its own package manager. The current
packaging approach doesn't allow such management. As a result the
package is unusable (see
https://github.com/NixOS/nixpkgs/issues/8650 and
https://github.com/NixOS/nixpkgs/issues/14903). In this version,
$ANDROID_HOME is _not_ set, allowing Android Studio to deal with the
Android SDK as it pleases (typically in $HOME/Android/Sdk).
- Android Studio downloads prebuilt binaries as part of the SDK. These
tools (e.g. `mksdcard`) have `/lib/ld-linux.so.2` set as the
interpreter. An FHS environment is used as a work around for that.
