bootstrap: Don't print "Skipping" twice

Bootstrap executes itself twice: once with DryRun::SelfCheck and DryRun::Disabled. Change it not to print the "Skipping" message if SelfCheck is enabled.

See https://github.com/rust-lang/rust/actions/runs/5503931599/jobs/10029625567?pr=113514#step:24:772.
