login: fix FDNAME in call to sd_pid_notify_with_fds()

$ git grep FDNAME
logind-session-device.c: ... "FDNAME=session-", sd->session->id);
logind-session-device.c: ... "FDNAME=session", sd->session->id);

Oops.

Fixes #8343.  Or at least a more minimal reproducer.  Xorg still
dies when logind is restarted, but the Xorg message says this
is entirely deliberate.

(This could also be the reason I hit #8035, instead of the race
condition I originally suggested).
