    test: Increase timeout for starting ftp server
    
    Currently, the test suite waits for starting the ftp server 5 seconds.
    This seems is not enough for GitLab CI as it randomly fails with "timed
    out waiting for test FTP server". Let's try to increase the timeout
    from 5 to 15 seconds in the hope that will fix the random failures.
