[PATCH v2 6/8] tests: mark & fix tests broken under GIT_TEST_PROTOCOL_VERSION=1

["Ævar Arnfjörð Bjarmason" <avarab@gmail.com>]

There's one t5400-send-pack.sh test which is broken under
GIT_TEST_PROTOCOL_VERSION=1. It's easier to just coerce it to run
under protocol 1. The difference in the output is that there'll be a
"version 1" line which'll make the subsequent "test_cmp". See
protocol.version in git-config(1) which notes that "1" is just "0"
with a version number.  the trace output will include fail.

Similarly in t5601-clone.sh we'll be passing an option to ssh, but
since so many tests would fail in this file let's go above & beyond
and make them pass by only testing the relevant part of the output.
