[PATCH 2/3] tests: mark tests broken under GIT_TEST_PROTOCOL_VERSION=1

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

A few tests are broken under GIT_TEST_PROTOCOL_VERSION=1, which as
protocol.version in git-config(1) notes is just the
GIT_TEST_PROTOCOL_VERSION=0 with a version number.

All of these cases look OK to me, and don't seem to show any
regressions or other behavior differences that are unexpected. These
tests are either testing exact v0 trace output, or trying to test the
v2 protocol.
