Android kernels with CONFIG_ANDROID_PARANOID_NETWORK extensions set
require users to have a few special group IDs before getting network
access. Unfortunately, we need to use nightly to get access to the
.groups() method.
Add tools for launching a root shell on the device, and for sending
serial commands to the device. Extend the make.sh script to push those
and configure a root shell. Commands can now be executed as root via:
adb shell rootshell -c \"touch /tmp/test\"
allowing automatic configuration of the tooling.
