attempt to execute su and check return code

This could potentially be detrimental for anyone that uses the library. According to this StackOverflow answe, executing su using Runtime.getRuntime().exec actually creates a new process each time it is executed.

@andrewjli The comments on that stackoverflow post indicate that this bug can be worked around if you use ProcessBuilder instead of Runtime.getRuntime().exec("su"). Suggest anyone attempting to implement it using something like the following

new ProcessBuilder().command("su").start()
