Subject: [PATCH] Set XAUTHLOCALHOSTNAME in sessions

While FamilyWild avoids that hostname changes break xauth, this doesn't help
with Xtrans (used for ICE). Xtrans always uses the current host name for
setting $SESSION_MANAGER and for a successful connection this has to match
the current hostname (or $XAUTHLOCALHOSTNAME, see p_xauth.diff in xtrans)
on client connection attempts as well. By setting XAUTHLOCALHOSTNAME here,
it's likely that it equals the hostname set by the session manager later
(e.g. ksmserver).
