android-rebuild.sh: Fix build server builds.

Our build servers use a more recent version of Ubuntu than the
one used on our workstations (14.04). As such, they have a different
C++ standard library runtime that isn't binary compatible with the
one expected by lib[64]OpenglRender_unittests.

This temporarily disables the unit-test until I find a better
solution in order to fix the build.
