Remove docs mention of PGREALM variable

This variable was only used with Kerberos v4. That support was removed
in 2005, but we forgot to remove the documentation.

-      PGREALM sets the Kerberos realm to use with
-      PostgreSQL, if  it is different from the
-      local realm.  If PGREALM is set,
-      libpq applications will attempt
-      authentication  with  servers for this realm and use separate ticket
-      files to avoid conflicts with local ticket files.   This
-      environment  variable is only used if GSSAPI authentication is
-      selected by the server.
