[ixpmanager] Issues with MRTG in Ubuntu 18.04

[Mauricio Oviedo]

Hi Nick,

Thanks, it worked correctly after creating the directory. However, after
rebooting the folder is deleted.

If I point the lock file to a different directory MRTG starts fine after
rebooting:

--lock-file /tmp/mrtg_l

Another approach could be to create the /var/lock/mrtg folder at start or
simply use just /var/lock...

 What do you think?
