mm/Kconfig: Re-add HAVE_USERSPACE_LOW_MEMORY_KILLER 



When Android has a userspace low memory killer, we want to configure
certain parts of the reclaim paths in the kernel.
HAVE_USERSPACE_LOW_MEMORY_KILLER can be used to perform this configuration,
and was removed when reverting a patch that defined it.  Re-add it.

	  Configures parts of the reclaim paths in the kernel when Android

	  has a userspace memory killer.  This configuration is done for

	  functional (e.g. ensuring the OOM killer doesn't run at certain

	  points) and performance purposes (e.g. preventing log-spew

	  when the OOM killer and userspace memory killer both have the

	  potential to run).
