Fix 'updating packages' reference in ports.html

The 'Managing Installed Ports' section of ports.html describes using
pkg_add -r to update packages. Since 3.9, this is no longer
necessary, and using pkg_add -u is simpler. faq15.html only mentions
-r, and describes using -u. It seems ports.html should do the same.

The diff following my .sig supplements the old instructions. Since
3.8 will only be supported for a few more weeks, this may be
redundant. A better option might be to simply replace the old
instructions.

Thanks!

 This is slightly inconvenient, as packages may trigger dependencies, and 
 you may have to remove a large subset of packages for an update.
+
+<p>
+As of OpenBSD 3.9, to update a package you can simply use 
+<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=pkg_add&amp;sektion=1&amp;format=html">pkg_add(1)</a> 
+with the <b>-u</b> switch:
+
+<blockquote><pre>
+$ <b>sudo pkg_add -u</b>
+</pre></blockquote>
+
+<p>
+With no package name and the <b>-u</b> flag, all installed packages
+will be updated. You must correctly set <tt>PKG_PATH</tt> in order
+for package updates to work. Consult the FAQ entry <a
+    href="faq/faq15.html#PkgUpdate">Updating installed packages</a>
+for more information.
