android-studio: add tar as a makedepends
https://github.com/void-linux/void-packages/pull/18625

Description:
android-studio was updated to 3.5.3 in void-packages 2 months ago ( #17265). Although this change was merged and travis checks passed, when I ran `xbps-install -S android-studio`, I got version 3.3.2_1. When I tried to build 3.5.3 from void-packages using `./xbps-src pkg android-studio`, I found that tar was missing.

Adding tar as a makedepends fixes this issue.
