[Buildroot] [git commit branch/2020.02.x] package/sysrepo: fix SysV init script

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=1f0116e44890257ca280e5420cb9f92a0e81d33d
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2020.02.x

The current script (S51sysrepo-plugind) is not able to stop the daemon.

Possible options to fix the problem:

A) By adding the "-m -p $PIDFILE" option to start the pid file will be
   created but it will not contain the correct PID used by the daemon.
   This is obviously because the daemon forks.
B) By not starting the daemon in background (sysrepo-plugind -d) and
   let do it by start-stop-daemon with "-b" option. But then the log
   messages of the daemon will not longer ends in the syslog but to stderr.
C) Start the daemon without a pidfile and stop the daemon with the
   "-x" option.

The only valid option is C to fix that.
