Fix examples of how to use "su" while starting the server.

The syntax "su -c 'command' username" is not accepted by all versions of
su, for example not OpenBSD's.  More portable is "su username -c
'command'".  So change runtime.sgml to recommend that syntax.  Also,
add a -D switch to the OpenBSD example script, for consistency with other
examples.  Per Denis Lapshin and Gábor Hidvégi.
