    systemctl: fix corrupted output of units
    
    On some systems the list of units in systemctl output came out wrong,
    all on one line and with missing descriptions.
    
    It turns out printf() really attempts to mmap 2G memory when INT_MAX is
    passed as the field width. On machines with small virtual memory
    without overcommit the mmap inside printf() failed.
    
    Do not use INT_MAX for unlimited width.
