[PATCH] tests: don't give unportable ">" to "test" built-in, use -gt

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

Change an argument to test_line_count (which'll ultimately be turned
into a "test" expression) to use "-gt" instead of ">" for an
arithmetic test.

This broken on e.g. OpenBSD as of v2.13.0 with my commit
ac3f5a3468 ("ref-filter: add --no-contains option to
tag/branch/for-each-ref", 2017-03-24).

Upstream just worked around it by patching git and didn't tell us
about it, I discovered this when reading various Git packaging
implementations: https://github.com/openbsd/ports/commit/7e48bf88a20

David, it would be great to get a quick bug report to
git@vger.kernel.org if you end up having to monkeypatch something
we've done. We won't bite, promise :)

As shown in that linked Github commit OpenBSD has another recent
workaround in turning on DIR_HAS_BSD_GROUP_SEMANTICS and skipping a
related test, maybe René can make more sense of that?

There's more patches in their ports which indicate possible bugs of
ours: https://github.com/openbsd/ports/tree/master/devel/git/patches/
