[RFC/PATCH] t9157-*.sh: Add an svn version check

Signed-off-by: Ramsay Jones <redacted>
---

This test fails for me, because my svn version(s) are too old (1.4.3 and 1.4.6), and
so I've got into the habit of running the tests with NO_SVN_TESTS=1. (which is a bit
of a shame in terms of test coverage, but it is *much* quicker!)

I don't know the details, but it seems that the 'svn merge' of this vintage does not
support the operations required by this test. Unfortunately, I don't know what the
minimum required version of svn is, so I'm hoping that someone can take this patch
and fix it up properly ...

ATB,
Ramsay Jones
