Code for #ifdef KERBEROS in rsh.c

[tsugutomo.enami%jp.sony.com@localhost]

Hi.

Most of kerberos support code is removed from rsh.c in rev. 1.29, but
there is still few lines of code enclosed by #ifdef KERBEROS.

Do we still need those code?  If not, I'll delete them before commiting
bug fix.

enami.
