Revert of Add apktool and apktool.jar to install-build-deps-android.sh

Revert of Add apktool and apktool.jar to install-build-deps-android.sh (patchset #4 id:60001 of https://codereview.chromium.org/1287133002/ )

Reason for revert:
Chromium devs don't have gsutil or gsutil credentials. install-build-deps-android.sh should be usable by public chromium developers.

Also, apktool has since been checked into the chromium checkout, so we no longer even need this.
