heptapod-ci: make Windows jobs manual again

The dance continues, we make the Windows tests optional once again since we
don't have Windows runners available anymore. We're working on getting new ones
in a more stable fashion, hopefully soon.

#require no-windows no-rhg

XXX-RHG this test hangs if `hg` is really `rhg`. This was hidden by the use of
`alias hg=rhg` by run-tests.py. With such alias removed, this test is revealed
buggy. This need to be resolved sooner than later.

Kludge to emulate timeout(1) which is not generally available.

  shutting down cleanly
  press ^C again to terminate immediately (dangerous)
  end of unsafe operation
