qemu_capabilities: Honour caps values formatting
    
    So the way we format this huge virQEMUCaps enum is we group the
    values in groups of five. And then at the beginning of each group
    we have a small comment that says what's the number of the first
    item in the group. Well, the last commit of 11b2ebf3e152 does not
    follow this formatting.
