Fix signal behaviour.

In my last change I made sure that the signal as reported from a truss
exit is the same as if truss wasn't between parent and trussed
program.  I was smart enough to not have it coredump on SIGQUIT but it
didn't ocur to me SIGSEGV might cause a coredump, too :-)

So get rid of SIGQUIT extra hack and limit coredumpsize to zero
instead.

Tested: still works, correct signal reported.  No more codedumps from
SIGSEGV in the trussed proces.  This file compiles cleanly on AMD64
(sledge).
