Add build/android scripts for Chromium TestShell

This is to match existing scripts for Content Shell.

There seem to be inconsistency in usages of 'testshell' vs. 'test_shell'. Since the build target is called 'chromium_testshell', and the package is called 'org.chromium.chrome.testshell', I'm leaning towards using this spelling.
