stream-clone-test: simplify the case where server disabled it
We have an option to disable it, we don't need to test it with all protocol
variants.
In addition there is little value in looking at the bytes to bytes details of
the reply. Such check is very fragile and consume a lot of time for little
value when adjusting formats, caches, and protocol.
#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.
