Move android-trace.h to include/android/

+ android-trace_common.h -> include/android/trace_common.h
  NOTE: trace_common.h is still in the top-level directory because
        the qtools first need to be updated to include the header
        at include/android/trace_common.h

+ trace.c -> android/
+ user-events.h -> include/android/
+ user-events-qemu.c -> android/
