Roopa Prabhu a33e94f72b Introduce a lock file in non-persistent storage /run/network/ifstatelock ...

to make sure the state file in persistent storage is cleaned up
correctly

Ticket: CM-7774
Reviewed By: CCR-3623
Testing Done: Tested statefile accross reboots

ifupdown2 state file was moved to /var/tmp because /var/tmp was tmpfs
and was large enough (100MB) for the state file. But it appears it has
changed (or is not consistent) across all platforms. We can move it
under /run, but /run again size varies on various platforms and it is
too small on some platforms.

This patch:
- continues to keep the ifupdown2 state file under /var/tmp (because it
needs the space)
- ntroduces a second level /run/network/ifstatelock file that stays on
non-persistant storage and is used to delete the state file at /boot up
