[Buildroot] [git commit] package/mender: fix sysv startup script

[Thomas Petazzoni]

commit: https://git.buildroot.net/buildroot/commit/?id=63739c5c25805816a20e7073e837e18854e83ada
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Mender is a service explicitly written for systemd and so it doesn't
fork on background, doesn't redirect outputs and doesn't create a pid
file by itself.
To make the service running correctly is therefore necessary to use the
-m switch of start-stop-daemon to create the pid file and -b option to
send the process to background.
Logging is preserved because the service will log anyway on syslog.
