Clarify process of how to get your FreeBSD.org Kerberos account setup for the first time

[sobomax]

Summary

Being quite late to the party, got a chance to setup my FreeBSD.org Kerberos account today. Found that the instructions is somewhat misleading, presenting both "% ssh kpasswd.freebsd.org" and "% kpasswd" methods as equivalent ways to set/reset your Kerberos password. Clarify that if you never used Kerberos before then "% ssh kpasswd.freebsd.org" is the way to get it going.

Switching this sentence around makes it sound less likely to fail: (ignoring indentation and wrapping)

Unless you have used the Kerberos-authenticated service(s) of the &os;.org cluster
previously, <errorname>Client unknown</errorname> will be shown.  This error means
that the <command>ssh kpasswd.freebsd.org</command> method shown above must
be used first to initialize the Kerberos account.</para>

@wblock revised in both places, thanks!

Looks good to me. Have you build-tested it? If not, I can take it and commit it.

No, I have not, that would be awesome if you can do it! The idea of installing docbook monstrosity onto my dev machine to test it gives me shivers. Seriously! :(
