binary search tool: Add android test scripts

Add android test scripts: boot test and interactive test. Boot test
waits for device to boot up and reach homescreen. Interactive test waits
for device to boot and asks user if the image is good or bad.

TEST=Run full bisection with boot test, test code paths with interactive
test
