run_test.sh: Mount /tmp into the unit test container

This change fixes an issue where tests would try to share configuration
with child containers via /tmp, but since those directories are not mounted and
a parent docker socket is used the containers created this way would
receive incorrect mounts. This fixes issues with SniProxy tests.

Fixes #28
