ar01: Rewrite to the new library

Also drop a few testcases that were obviously wrong.

There are two kinds of dropped testcases:

* The option -p does not affect option foo

  The checks were completely bogus in this cases.

* The ar completed without interruption when signaled

  These testcases started ar in bacground then waited for the archive
  file to appear and finally tried to send a signal to the ar process.

  The obvious problem here is that at the point the test tried to send
  the signal the ar was no longer running.
