hikey/hikey960: Fix libmemtrack for treble

When enabling FULL_TREBLE, libmemtrack starts
having build issues. So this patch fixes it
by adding libhardware to the build.

Credit for this patch goes to Vishal Bhoj <vishal.bhoj@linaro.org>
who basically was the original author and magician
who got things working.

I've only refactored and split up his changes to help
with the submissions.
