package/nginx/S50nginx: Do not assume start-stop-daemon knows -R.

start-stop-daemon fails on -R when not compiled with
CONFIG_FEATURE_START_STOP_DAEMON_FANCY.  Thus, do not rely on -R
during stop to avoid a race condition during restart.

Use a sleep 1 during restart instead, as suggested by Peter Korsgaard
in <87bmluk4bm.fsf@dell.be.48ers.dk>.
