    Increase default file handle limits for virtlogd
    
    The initial assumption was ~2 files per guest, but some common setups
    like Openstack drive up to 4 files per guest.
    
    E.g. on Arm where the following XML leads to 4 file handles:
        <serial type='file'>
          <source path='/var/lib/nova/instances/7c0dcd78-.../console.log'/>
          <target port='0'/>
          <alias name='serial0'/>
        </serial>
        <console type='file'>
          <source path='/var/lib/nova/instances/7c0dcd78-.../console.log'/>
          <target type='serial' port='0'/>
          <alias name='serial0'/>
        </console>
    
    With that in mind and the target to support 4k guests by default we
    should raise the limit to 16k.
