brillo_update_payload: Disable Brillo deltas for minor version <= 2.

Support for deltas in the client landed for Brillo with minor version
3. While there shouldn't be any clients using such old version,
developpers may have upload these images to our server and deltas are
expected to fail.

This CL makes brillo_update_payload exit with error code 100 when the
source image does not support deltas.

Bug: 26193066
TEST=`brillo_update_payload` from old image failed and returned exit code 100.
