 android/lowmemorykiller: Wait for memory to be freed

The memory reclaim code needs to give time to the system to
return the memory from a killed process otherwise the memory
reclaim code could run continuously, in multiple threads,
which could starve both the watchdog thread and the thread
which is responsible for returning the memory from the
killed process.

 Staging: android: binder: Add binder buffers to kmemleak

binder_buffer. This could cause kmemleak to report them as
unreferenced.
