fix build when ENABLE_CLI_INTERACT_AUTH is disabled The session.h defines clientsession.cipher_none_after_auth only when ENABLE_CLI_INTERACT_AUTH is defined, but cli-session.c will always try to set that member. export cipher_none_after_auth all the time.

/* LibTomMath, multiple-precision integer library -- Tom St Denis
 *
 * LibTomMath is a library that provides multiple-precision
 * integer arithmetic as well as number theoretic functionality.
 *
 * The library was designed directly after the MPI library by
 * Michael Fromberger but has been written from scratch with
 * additional optimizations in place.
 *
 * The library is free for all purposes without any express
 * guarantee it works.
