Michael Achenbach 3afea88feb [gcmole] Make wrapper backwards-compatible to gcmole modes
In a follow up we want to introduce a mode for just collecting or
processing. In the infrastructure however, we still call the wrapper
script with old arguments on release branches. This ensures that
we stay backwards compatible.
