[RFC PATCH] tests: fix PATH for GIT_TEST_INSTALLED tests

[Guillaume Maudoux <layus.on@gmail.com>]

From: Guillaume Maudoux <layus.on@gmail.com>

When running tests on an existing git installation with
GIT_TEST_INSTALLED (as described in t/README), the test helpers are
missing in the PATH.

This fixes the test suite in a way that allows all the tests to pass.

This is more a bug report than a real patch. The issue is described
above and this patch does solve it. I however think that someone with
more knowledge should refactor all that chunck of code that was last
changed in 2010.

In particular, it seems that the GIT_TEST_INSTALLED path does not use
bin-wrappers at all. This may imply that --with-dashes also breaks
tests.
