[PATCH 1/3] test-lib: handle TEST_OUTPUT_DIRECTORY with spaces

[Jeff King <peff@peff.net>]

We are careful in test_done to handle a results directory
with a space in it, but the "--tee" code path does not.
Doing:

  export TEST_OUTPUT_DIRECTORY='/tmp/path with spaces'
  ./t000-init.sh --tee

results in errors. Let's consistently double-quote our path
variables so that this works.

I imagine nobody cares much about this, but I just happened to notice it
while writing the rest of the patches (and it's obviously quite easy to
fix).
