sim: run: punt!
Now that all targets have been converted to nrun, we can finally punt
this old inconsistent interface.

A few stray references to the old run were sprinkled about; clean them
up in the process.

We leave behind the run(1) man page mostly so that we get it updated for
the new nrun interface.
