TAP harnesses don't need to read test-results/*, since they keep track of the number of passing/failing tests internally. Skip the generation of these files when HARNESS_ACTIVE is set.

It's now possible to run the Git test suite without writing anything to the t/ directory at all if you use a TAP harness and the --root switch:

    cd t
    sudo mount -t tmpfs none /tmp/memory -o size=300m
    prove -j9 ./t[0-9]*.sh :: --root=/tmp/memory

The I/O that the ~500 test-results/* files contributed was very minimal, but I thought this was worth mentioning.

This one fell through the cracks, and conflicted with Thomas's later "Only run aggregate-results over actual counts" patch.

Please apply it, it keeps conflicting with local changes I have to the test-lib.sh
