android-studio: repackage in an FHS environment

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.
