Note that this will conflict with tr/perftest, which is already in next.
It had a similar override, but then made do with the existing
GIT_TEST_INSTALLED facility.  I think you do need the above here,
because you are not sourcing test-lib from the directory where the test
lives.  It may then be cleaner to again use GIT_BUILD_DIR in
t/perf/perf-lib.sh since it does not require knowledge (outside of
test-lib) that $GIT_BUILD_DIR/bin-wrappers/ holds the binaries.
