tests: respect $TMPDIR when creating unix domain sockets

When running on termux, where $TMPDIR isn't /tmp, running the tests
failed, since the server config tried creating sockets in /tmp, without
checking the temp dir config. Use the TMPDIR variable that makes it find
the correct directory everywhere [0]
