cli_tests.cfg: update the DryRun rsync-command assertion for
install_sdp.sh's new '.p4config' exclude.
//p4-sdp/main change 33548 added '--exclude=.p4config' to
install_sdp.sh's local-copy rsync (fixing a real bug where a
DVCS-clone's own local .p4config, with a broken rsh: P4PORT, could
leak into an installed SDP tree). This test's literal-string
assertion on the logged rsync command line predates that fix and
was failing (Test 26) on every platform in today's full-suite run
-- not a regression, just a stale expected string. Updated to match
the corrected rsync line.
