    mqueuefs: fix statfs report to not signal file system full
    
    Synthetic file systems that do not actually allocate file system
    blocks or inodes should report that they have space available and
    that they provide 0 inodes, in order to prevent capacity monitoring
    tools from warning about resource exhaustion.
    
    This has been fixed in all other synthetic file systems in base in
    commit 88a795e80c0, but this file was overlooked since its name does
    not indicate that it also provides a file system.
