[PATCH] test-lib: Ignore --quiet under a TAP harness

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

Running the tests with --quiet under a TAP harness will always fail,
since a TAP harness always needs actual test output to go along with
the plan that's being emitted.

Change the test-lib.sh to ignore the --quiet option under
HARNESS_ACTIVE to work around this. Then users that have --quiet in
their GIT_TEST_OPTS can run tests under prove(1) without everything
breaking.
