Make Hardware class platform specific.
The Hardware class abstracts the interaction with the actual hardware
which is inherently platform-specific. This patch implementes a stub
version for Android and moves the Chromium OS implementation, handling
both with the same public factory method.
Bug: 23084776
TEST=emerge-link update_engine; `mma -i` builds the stubs.
