[PATCH v2] t0005: work around strange $? in ksh93 when program terminated by a signal

[Johannes Sixt <j.sixt@viscovery.net>]

From: Johannes Sixt <j6t@kdbg.org>

ksh93 is known to report $? of programs that terminated by a signal as
256 + signal number instead of 128 + signal number like other POSIX
compliant shells. (ksh's behavior is still POSIX compliant in this regard.)

Thanks for you input!
