test job is renamed to end with a '.stress-failed' suffix.

You can also set the GIT_TEST_INSTALLED environment variable to
the bindir of an existing git installation to test that installation.
You still need to have built this git sandbox, from which various
test_oid_init or test_oid_cache. Providing an unknown key is an
error.

+ This is often seen in modern UNIX but some platforms lack it, so
+ the test harness overrides the platform implementation with a
+ more limited one. Use this only when feeding a handful lines of
+ output to the downstream---unlike the real version, it generates
+ only up to 99 lines.
