Build unittests in Brillo.

Many unittests do not pass for simple reasons that will be addressed
later. This CL includes all the changes to make the unittests build.
In particular, the generated DBus mocks, required to build several
unittests are now included here.

The dbus-constants.h files were moved to the system_api repo, so they
can be removed from here.

The unittest build is only enabled for Brillo targets, since non-Brillo
targets don't even build DBus.

Bug: 26955860
TEST=`mmma` on edison-eng (and aosp_arm-eng).
