runtests: add --rsync-bin2 / --expect-result for version-mixing tests

Let the suite run with two rsync binaries so the current build can be
tested against the actual old code of a previous release, rather than
only forcing the current binary to speak an old protocol (check29/30).

  --rsync-bin2 PATH  exports RSYNC_PEER, the binary used for the SERVER
                     side of two-sided transfers (the daemon process and
                     the remote-shell --rsync-path target). Defaults to
                     RSYNC, so single-binary runs are byte-for-byte
                     unchanged.
  --expect-result F  the manifest's listed tests ARE the run set; each
                     test's actual outcome (pass/skip/fail/xfail) is
                     compared to its expected one and any mismatch --
                     including an unexpected pass (xpass) -- fails the
                     run. --expect-skipped and the default exit logic
                     are untouched.

rsyncfns gains the RSYNC_PEER global and launches the daemon with it
(start_rsyncd / start_test_daemon, the latter with an optional rsync_cmd
override used by the reverse-direction test); the remote-shell tests
pass --rsync-path={RSYNC_PEER}. All no-ops when no peer is selected.

Direction is fixed: the current binary always drives (only it
understands the new test scripts); the old binary is only ever the
server/daemon side.
