Scriptname_flags doesn't work because the port maintainer didn't write the 
startup script so that it parses rc.conf for variables.  You can edit the 
script like this:

command_args="-s"

When rc.subr runs scripts, it runs them like this:

${command} ${command_args} ${command_flags}

Or you can add this to the startup script and then use flags in rc.conf:
load_rc_config openntpd

openntpd_flags=${openntpd_flags:-""}

(In that order.)

Then place openntpd_flags="-s" in rc.conf.

Just remember that every time the port is updated, your changes will be 
overwritten, so you'll need to make a backup or leave a note to yourself 
somewhere so you remember to alter the new script.
