Failed to rename package name in buildbot scripts. Broke buildbots.

> Add apk for running content_browsertests
>     
> Split off org.chromium.content_shell into:
>       org.chromium.content_shell - content shell java code, builds a jar, directory structure similar to other jar targets
>       org.chromium.content_shell_apk - application code to build content_shell_apk, directory structure similar to that of android application
>       org.chromium.content_browsertests_apk - application code to build content_browsertests_apk
> 
> Also splitting content/shell/android/res into:
>   - content/shell/android/java/res 
>   - content/shell/android/shell_apk/res
> 
> Both content_shell_apk and content_browsertests_apk will depend on content_shell_java target to include java/res needed to show a shell based browser.
>     
> I will do another CL to move The java files for content_shell_tests_apk to content_shell_apk package.
