Android 'su' Privilege Escalation

This module uses the su binary present on rooted devices to run
a payload as root.

A rooted Android device will contain a su binary (often linked with
an application) that allows the user to run commands as root.
This module will use the su binary to execute a command stager
as root. The command stager will write a payload binary to a
temporary directory, make it executable, execute it in the background,
and finally delete the executable.

On most devices the su binary will pop-up a prompt on the device
asking the user for permission.
