Subject: [PATCH] test-driver.py: Share the shared dir between VMs

This changes the python test driver to match the behavior of the perl
test driver.  I.e. the directory mounted into /tmp/shared should be the
same for all machines.

This probably fixes many tests, but I found this while investigating
failures in nixos/tests/ceph-multi-node.nix.
