debian: Fix rpc.mountd start

This work is part of Debian integration effort for AIO-DX.
When booting controller-1 from controller-0, part of controllerconfig
service execution some dirs are nfs mounted, and necessary data
transfered from the nfs mounted location.
The rpc.mountd component is not properly started up. Invalid flags
are passed to service start call. This prevents the nfs mount from
happening, leaving the system in an unstable state.

Fix the required service start.

One of the symptoms is that sysinv cannot update the inventory
information for interfaces(and more) on controller-1.
Tests on AIO-DX:
PASS: install controller-1 from controller-0
PASS: system interface-network-list controller-1
      shows the interfaces
