Fix novacomd start on emulator

:Release Notes:
Since novacomd on the emulator relies on eth0, change the start-on to
account for that.

:Detailed Notes:
Previously, novacomd was trying to start on 'stopped bootmisc' which is
too early in VirtualBox.  Changing to 'started connman' plus a
(somewhat ugly) 3 second delay results in more reliable startup.

:Testing Performed:
Tested in verification build 450

:QA Notes:
To find the ID of the emulator, use 'novacom -l':
novacom -l
58355 7788a6c82a99ac161d98d56e78d12a81f93cca74 tcp emulator
Then 'novaterm -d 7788a6c82a99ac161d98d56e78d12a81f93cca74'.

:Issues Addressed:
[CTO-421] emulator could not boot
