Subject: [PATCH 1/1] tty: disassociate_ctty() sends the extra SIGCONT

Starting from v3.10 (probably f91e2590 "tty: Signal foreground
group processes in hangup") disassociate_ctty() sends SIGCONT
if tty && on_exit. This breaks LSB test-suite, in particular
test8 in _exit.c and test40 in sigcon5.c.

Put the "!on_exit" check back to restore the old behaviour.
