Android NDK9e / Android 4.3 fixes and added Logcat output :)

Hi,

I've fixed some compiling issues with Android NDK9e, made the build process easier and fixed the README. I've added logging to LOGCAT for the example instead of logging to a file.

Verified and working with Samsung Galaxy GT-I9300 with latest 4.3 firmware with SELinux Kernel and MobiCore code injection using Android NDK9e. The hook cleanup still needs to be fixed as it seems to crash the process after freeing the hook.

Kind regards and thanks for your great code,

P.S.: injectso isn't android 4.3 compatible in terms of system daemons :)
