[Android] Use a script on the device for creating library symlinks

On new versions of Android, re-installing an APK creates a new /lib/
folder for native libraries. This means we need to recreate all the
symlinks in that directory (not just the ones that have changed).

To make all these links quickly, it should run as a single adb command.
To make that simple, we first create a simple script that, when run,
creates all the symlinks for an APK. Then, after any install, we send a
single adb command to run that script.

This also requires that the apk_install script only triggers its
dependents when it actually installs an apk.
