Subject: test-lib: Allow overriding of TEST_DIRECTORY

test-lib: Allow overriding of TEST_DIRECTORY

Tests that test the test-lib.sh itself need to be executed in the
dynamically created trash directory, so we can't assume
$TEST_DIRECTORY is ../ for those.

As a side benefit this change also makes it easy for us to move the
t/*.sh tests into subdirectories if we ever want to do that.
