busybox: Improve syslog restart handling
We're seeing races on the autobuilder where syslogd fails to shut down fast enough to be restarted leading to failures. Add some checks to ensure when restarting that processes exit before being restarted. (From OE-Core rev: 04de384256ad321834cf5e3dbb9a8d3ea2ab66c2) Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
