[OE-core] [PATCH] dropbear: Do not kill client connections on stop and restart

[Holger Hans Peter Freyther]

Use the pidfile functionality of start-stop-daemon to only kill
the dropbear server process and not the active client connections.

OE-classic used to have this functionality, a patch for it was
applied in revision 6adaccf00601e1bc3ce1ede5417eabcdf1671768.
