Andrew Tridgell ad3bfab05d ci: version-mixing workflow, expect manifests, check-progs target ...

Adds .github/workflows/ubuntu-version-mix.yml (ubuntu-latest) and a
per-release manifest testsuite/expect/rsync_<ver>.expect for each of the
nine peers. The workflow builds the current rsync, then runs the two-
sided suite against every old binary over both the pipe and --use-tcp
daemon transports. All peers run in a SINGLE looped job (not a matrix)
so the PR shows one check line; each peer/transport is a foldable log
group and a failure annotates which one broke.

A new phony `check-progs` target builds rsync plus the test helper
programs and check symlinks without running the suite -- the build half
of `make check` -- so the workflow's direct runtests.py invocation has
the helpers it needs.

Notable expected results encoded in the manifests:
 - The four May-2026 security tests xfail against every released peer:
   the suite demonstrates each release is vulnerable to those findings
   while current master is fixed.
 - symlink-dirlink-basis xfails on 3.4.0/3.4.1 (issue #715: their
   secure_relative_open O_NOFOLLOW-confines the basedir, breaking a -K
   dir-symlink update; current master fixes it with secure_basis_open).
 - Older peers carry more xfails for options/negotiation they lack;
   2.6.0 (protocol 27) fails most daemon tests. reverse-daemon-delta
   passes against all peers, confirming backward compat down to 2004.
