bitbake: lib/bb/progress: avoid possibility of start event being reported twice

In MultiStageProgressReporter, set a guard when we start the progress
so that it can't happen more than once. This fixes "Initialising
tasks.." being shown twice in succession when running bitbake in
non-interactive terminal mode.
