    QemuImgInfo: Fix inconsistent value format of encrypted

    The qemu-img info command shows the encrpyed field in different formats
    according to the output format. When the default human format is used
    the field can be 'yes' or None while when json format is used the same
    field can be True or False.
    This change ensures the corresponding attribute has the consistent
    format regardless of the output format used.
