    Fix Travis-CI build issue with group-writable PYTHON_EGG_CACHE dir.
    
    Travis-CI issue #1748 [0] was causing non-deterministic CI test
    failures, particularly in the lib/bridgedb/test/test_https.py
    integration tests which use the Python mechanize module to test the
    HTTPS server. [0]
    
    This is a known Python security issue, particularly for WSGI server
    setup. [2] [3] The fix is quite simple, just set the PYTHON_EGG_CACHE
    environment variable to something unique to each CI build and ensure
    that the PYTHON_EGG_CACHE directory exists.
    
     * FIXES issues with non-deterministic Travis-CI test failures due to a
       known security hole in shared Python .egg cache directories.
