    automation: fix false success in qemu tests
    
    Fix flaw in qemu-*.sh tests that producess a false success. The following
    lines produces success despite the "expect" script producing nonzero exit
    status:
    
        set +e
    ...
        ./automation/scripts/qemu-key.exp | sed 's/\r\+$//'
        (end of file)
    
    The default exit status for a pipeline using "|" operator is that of the
    rightmost command. Fix this by setting the "pipefail" option in the shell,
    and removing "set +e" allowing the expect script to determine the result.
