test-lib: handle TEST_OUTPUT_DIRECTORY with spaces

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.
