[PATCH 0/3] t0000 cleanups

When I want to debug a failing test, I often end up doing:

  cd t
  ./t4107-<tab> -v -i
  cd tra<tab>

The test names are long, so tab-completing on the trash directory is very helpful. Lately I've noticed that there are a bunch of crufty trash directories in my t/ directory, which makes my tab-completion more annoying.

It turns out they're leftovers from t0000 running, due to a bad interaction with some other fixes from last April. The first patch fixes that.

The second patch is a follow-on cleanup enabled by the first.

The third is an unrelated cleanup that I noticed when I ran t0000 47 times in a row. :)

  [1/3]: t0000: set TEST_OUTPUT_DIRECTORY for sub-tests
  [2/3]: t0000: simplify HARNESS_ACTIVE hack
  [3/3]: t0000: drop "known breakage" test
